Lockheed Martin Building LRASM Top Side Launcher Prototype for LCS OTH RequirementSNA 2017 Show NewsPublished: Thursday, 19 January 2017 22:02 At the Surface Navy Association's (SNA) National Symposium recently held near Washington DC, Lockheed Martin was showcasing its Long Range Anti-Ship Missile (LRASM) in three configurations: Air launched (as part of OASUW Increment 1 for B-1B and F/A-18), VLS launched (from Mk41) as well as top side launchers fitted on a LCS Frigate based on the Freedom-class LCS. Lockheed Martin LCS Frigate scale model at SNA 2017 featured LRASM top side launchers A draft request for proposal (RFP) for the LCS Frigate over the horizon (OTH) weapon requirement was issued in December 2016, with the final RFP expected by the end of January 2017. The contenders to answer the LCS OTH requirement are Kongsberg (teamed with Raytheon) with the NSM, Lockheed Martin with the LRASM and Boeing with the Harpoon ER. Each company was showcasing their anti-ship missile solution at SNA this year.“The next opportunity for LRASM is an emmerging opporunity called the frigate over the horizon weapon RFP [...] for that platform we need a top-side launcher [...] we have a concept for that launcher, it is a modular system where you can have 2 missiles on a launcher or a four-pack [...] we are building our first top-side launcher prototype and are planning for a flight test in the summer of this year" said Scott Callaway, Surface-Launched LRASM program manager at Lockheed Martin. The distributed lethality concept (one of the themes of the symposium) was introduced by Vice Admiral Thomas Rowden, the Commander of the U.S. Navy's surface forces. It can be summarized by fitting more weapons on more vessels in order to "deceive the enemy, target the enemy, and destroy the enemy".The Lockheed Martin LCS Frigate model on display at SNA 2017 featured 8x LRASM missiles in two launchers located between the Mk44 30mm guns and funnels (note the two MK 53 Nulka decoy launchers placed right next to the LRASM launchers too). The frigate model still features the 2x 30 cells for Longbow Hellfire missiles from the LCS Surface-to-Surface Missile Module (SSMM).The LRASM is a long-range subsonic cruise missile designed for better range and survivability than current anti-ship weaponry. This missile development program is a joint effort of the Defense Advanced Research Projects Agency, Naval Air Systems Command and the United States Air Force. The air launched variant, designated AGM-158C, first phase of inflight tests was completed in early 2016. Lockheed Martindemonstrated LRASM’s Surface Launch Capabilities in July 2016, from the U.S. Navy Self Defense Test Ship (SDTS).

Video: BAE Systems Naval Weapon Systems at SNA 2017 - Railgun - HVP - Mk45 - Mk110Published: Monday, 23 January 2017 18:53 At the Surface Navy Association's (SNA) National Symposium recently held near Washington DC, BAE Systems was showcasing its entire range of naval weapons systems to support the US Navy's distributed lethality concept. Mk 45 Mod 4 Naval Gun System scale model Electromagnetic RailgunThis fascinating technology, which uses high-power electromagnetic energy instead of explosive chemical propellants to launch projectiles farther and faster than any previous system, is currently in Phase 2 of the program. During this phase, BAE Systems will advance the railgun by maturing the launcher and pulsed power from a single shot operation to a multi-shot capability. Auto-loading and thermal management systems will also be incorporated. BAE Systems received a $34.5M contract from ONR in 2013 to pursue these efforts.Hyper Velocity Projectile (HVP)The HVP is a next-generation, common, low drag, guided projectile capable of executing multiple missions for a number of gun systems. The high-velocity compact design relieves the need for a rocket motor to extend gun range. Firing smaller, more accurate rounds decreases the likelihood for collateral damage and provides for deeper magazines and improved shipboard safety. Video: BAE Systems naval weapons at SNA 2017Mk 45 Mod 4 Naval Gun SystemThe 5-inch (127-mm) 62-caliber Mk 45 Mod 4 Naval Gun system is in U.S. Navy service today, and is ready to significantly enhance Naval Surface Fire Support (NSFS) and overall mission performance. Major upgrades of the Mk 45 Mod 4 include a 62-caliber barrel, strengthened gun and mount subsystems, advanced control system enhancement, and a reduced signature, low maintenance gun shield.Mk110 Naval Gun SystemBAE Systems' 57MM Mk110 (internationally known as the Bofors' 57Mk3) provides high survivability and tactical freedom at all levels of conflict. In the littoral scenario the gun must have the capability to engage threats that were impossible to engage with conventional gun systems. Survivability in such an environment requires an extremely flexible weapon system. The 57mm Mk110 has this flexibility, which is proven by the fact that it is the deck gun of choice for the US Coast Guard’s National Security Cutter and offshore patrol cutter classes of ships, as well as for the US Navy’s LCS ships.

Norway opts to buy German submarinesSebastian Schulte, Bonn - IHS Jane's Defence Weekly08 February 2017 Norway's decision, announced on 3 February, to procure four Type 212NG submarines and enter a strategic partnership with the German Navy and Germany's naval industry will have major implications for both countries' defence industries.As part of the agreement Germany will also buy two submarines in the same NG (Norway-Germany/Next Generation) configuration. The deal could also be expanded to meet Dutch and Polish requirements, as both countries have been in continuous negotiations with Norway. So far Poland has signed industrial co-operation agreements with Saab/Kockums and DCNS.The decision is a much needed win for Thyssenkrupp Marine Systems (TKMS), after the company lost an important bid to build Australia's next generation of submarines in April 2016. As a result the Norwegian tender, where French and German offers had been down selected, it was considered a 'must win' by Berlin and TKMS. There had been concern that if France was again successful that TKMS would come under commercial pressure and could be subject to a French takeover bid. Norway and Germany's partnership to buy submarines from TKMS has accordingly strengthened the company to the point that such consolidation seems less far off than before.Another implication from the deal affects Germany's missile industry. Jane's understands that as part of the German-Norwegian deal the Kongsberg Naval Strike Missile (NSM) has been chosen for Germany's Multirole Combat Ship (MKS 180), in lieu of the previously planned Saab Bofors Dynamics/Diehl BGT Defence RBS 15 missile.

U.S. army engineers have designed a new muzzle break LBOP for M119 105mm towed howitzer.Published: Thursday, 16 February 2017 08:29U.S. Engineers from Watervliet Arsenal have designed a 105 mm low blast overpressure muzzle brake, or LBOP. It's the first large caliber muzzle brake designed specifically for an existing gun system. Muzzle brake designs for large caliber have historically been for brand new cannon designs, but the LBOP was designed around the existing M119 howitzer platform. The M119 105mm howitzer, outfitted with the LBOP muzzle brake, ready for live-fire testing at the Yuma Proving Ground in Arizona. (Photo Credit: US Army website) The designs are being developed at the Armament Research, Development and Engineering Center's Benet Laboratories at Watervliet. A muzzle brake achieves recoil reduction by redirecting propellant gasses rearward, explained Robert Carson, LBOP design engineer. It's similar to the thrust reversal used during the landing of a jet plane when the jet plane's engines redirect engine exhaust forward to reduce the jet's forward momentum.The more efficiently a muzzle break redirects propellant gasses to the rear of the gun, Carson explained, the greater the reduction in the recoil."It is important to the warfighter because it allows them to be more lethal by sustaining [a] higher number of rounds fired per day," said Alan Ng, LBOP program lead, "because the blast overpressure from this new muzzle brake that is experienced by the artilleryman is significantly lower." An Army Soldier assigned to Alpha Battery, 1-143rd Field Artillery, prepares to test fire an M119A3 105mm Howitzer at Camp Roberts, Calif., January 18, 2017. The LBOP muzzle break also reduces the auditory and non-auditory health hazards -- compared to the current muzzle brake on the M119, according to Carson. "The reduction in impulse noise [blast overpressure] varies between 13 percent to 48 percent at various quadrant elevations and crew locations," Ng said.The 105 mm LBOP muzzle brake would be used with the M119 Towed Howitzer during shorter range howitzer missions and training.The M119 Towed Howitzer is designed specifically for this 105 mm M20 cannon, but the technology can be engineered for other cannon platforms, such as a 155 mm.The M119 is a lightweight 105mm towed howitzer in service with the US Army. The howitzer provides direct and indirect fire support to the forces deployed in combined arms operations. The M119A2 is equipped with with a digital fire control system that includes an inertial navigation unit, guided-precision system technology and other features that will give the weapon the ability to determine its precise geographical location on its own.The digitized M119A2 includes a GPS-aided Inertial Navigation Unit, or INU, that knows where the weapon is at all times, so optical sites are not needed to determine location. The INU allows the Soldier to ready the howitzer and fire the first round in two to three minutes. The latest version, the M119A3 has received several significant upgrades that improve performance, maintainability and safety. The most recent upgrades incorporated into the current configuration include digital fire control; increased low temperature capability, from -25 to -51 degrees Fahrenheit; and the M20 breech.

Lockheed Martin's Modernized TACMS Missiles Successful in Two New Flight Tests DALLAS, Feb. 20, 2017 /PRNewswire/ -- Lockheed Martin's (NYSE: LMT) modernized Tactical Missile System (TACMS) missile continued its streak of successful flight tests with two recent flights at White Sands Missile Range, New Mexico. These tests represent the third and fourth consecutive successful trials of the modernized TACMS.In December, a modernized TACMS successfully engaged and destroyed a target in a 71-kilometer test. And in early February, a fourth modernized TACMS destroyed a target at White Sands at a range of more than 200 kilometers. In both tests, the TACMS missiles were launched from a High Mobility Artillery Rocket System (HIMARS) launcher."With our third and fourth consecutive successful modernized TACMS flights, I believe we have demonstrated that our production quality and new technology are ready to move forward," said Scott Greene, vice president of Precision Fires & Combat Maneuver Systems at Lockheed Martin Missiles and Fire Control. "These modernized TACMS missiles will allow our warfighters to quickly and accurately address imprecisely located targets on the battlefield."The missiles used in these two tests were produced at Lockheed Martin's Precision Fires Production Center of Excellence in Camden, Arkansas. As part of the U.S. Army's TACMS Service Life Extension Program, the modernized missile includes new state-of-the-art guidance electronics and added capability to defeat area targets without leaving behind unexploded ordnance. The TACMS modernization process disassembles and demilitarizes TACMS Block 1 and 1A submunition warheads, replacing them with new unitary warheads and bringing them into compliance with Department of Defense policy on cluster munitions and unintended harm to civilians. The modernization process also resets the missile's 10+ year shelf life.In December 2014, Lockheed Martin and the U.S. Army signed a $74 million contract to take existing TACMS missiles from inventory and modernize them.The TACMS platform provides maximum flexibility to quickly integrate new payloads and capabilities to meet current and future demands.With unsurpassed performance and an unwavering commitment to production excellence, TACMS is the only long-range tactical surface-to-surface missile ever employed by the U.S. Army in combat. TACMS missiles can be fired from the entire family of MLRS launchers.

Meet the Navy’s Enterprise Air Surveillance RadarEASR is the U.S. Navy’s next generation radar for aircraft carriers and amphibious warfare ships, providing simultaneous anti-air and anti-surface warfare, electronic protection and air traffic control capabilities.The radar delivers increased performance, higher reliability and sustainability, and lower total ownership cost than the radars they will replace.EASR leverages the highly-scalable design and mature technologies of AN/SPY-6(V) Air and Missile Defense Radar (AMDR), in a tailored configuration to deliver superior capability to meet the mission requirements of carriers and amphibious ships. It features:* Power, efficiency, size/weight, cost and reliability benefits of gallium nitride (GaN)* Digital beamforming and advanced algorithms for operation in high clutter, near-land, electromagnetic interference environments.* Built-in cyber resiliencyTHE HIGHLY CAPABLE, TRULY SCALABLE RADARSBoth EASR and AMDR are built with the same individual ‘building blocks’ called Radar Modular Assemblies. Each RMA is a self-contained radar in a 2’x2’x2’ box. These individual radar RMAs can stack together to form various size arrays to fit the mission requirements of any ship.AMDR is comprised of 37 RMAs – which is equivalent to SPY-1D(V) +15 dB in terms of sensitivity. To give this perspective, it means that SPY-6 can see a target of half the size at twice the distance of today’s radars.EASR is a 9 RMA configuration – which is equivalent to the sensitivity of the current SPY-1D(V) radar on today’s destroyers, and at only 20% of the size of the legacy SPS-48. These are considerable enhancements over the radars in service on current (and future) EASR-designated ship classes.Two variants of EASR will be provided (each face an identical 9-RMA array):Variant 1 – a single face, rotating radar* Upgraded capability replacing AN/SPS-48 and -49 air search radars* Primary sensor for ship self-defense and situational awareness* Designated radar for LHA-8 and LX(R)Variant 2 – three face, fixed array radar* Upgraded capability replacing AN/SPY-4 Volume Search Radar* Primary sensor for ship self-defense, situational awareness and air traffic control* Designated radar for CVN 78 Ford-class carriers, starting with CVN 79RELIABILITY AND AFFORDABILITYThe commonality - in both hardware and software – with SPY-6 offers a host of advantages, including performance, availability and reliability; maintenance, training, logistics and lifecycle support. Its open architecture design enables maximum use of commercial-off-the-shelf components and the seamless and rapid insertion of future technology.The radar’s performance and reliability are a direct result of more than 10 years of investment in core technologies, leveraging development, testing and production of high-powered Gallium Nitride (GaN) semiconductors, distributed receiver exciters, and adaptive digital beamforming. GaN components cost 34% less than Gallium Arsenide alternatives, deliver higher power density and efficiency, and have demonstrated meantime between failures at an impressive 100 million hours.Both variants of the radar have an extremely high predicted operational availability due to the reliable GaN transmit/receive modules, the low mean-time-to-repair, and a very low number of Line Replaceable Units. Designed for maintainability, standard LRU replacement in the RMA can be accomplished in under six minutes – requiring only two tools.

Rheinmetall promoting its Skynex air defence system in Abu DhabiPublished: Wednesday, 22 February 2017 08:05At IDEX 2017, the German Company Rheinmetall, one of the world’s foremost supplier of state-of-the-art air defence systems is showcasing its new approach to the below-Patriot threat spectrum in five highly realistic scenarios. A solution for neutralizing projectiles that cannot be stopped with larger, missile-based air defence systems. Rheinmetall's Oerlikon Revolver GUN Mk3 Experience gained in current conflicts shows that certain threats cannot be effectively countered with large, missile-based air defence systems, while other projectiles slip past the defensive shield as ‘leakers’. First and foremost, these include mortar shells, small rockets, drones and similar projectiles from the “low, slow, small spectrum”.Forming the basis here is the Oerlikon Skynex, the Rheinmetall Group’s ground-based, fully networked, future air defence system first presented at Eurosatory 2016. It features open, modular architecture, forging a wide array of sensors and effectors into a highly effective, extensively automated system. Centralized and decentralized operation and command are equally possible, and the system can be configured for either a tactical or operational role. Highly mobile, the Oerlikon Skynex is ready for action in very short order. This makes it ideal for defending sensitive infrastructure and areas from virtually every form of aerial threat, both symmetric and asymmetric – around the clock and in all weathers. It instantly detects incoming rockets and artillery and mortar (RAM) rounds and even very small drones, engaging them with scalable intensity.The core element of Skynex is the Oerlikon Skymaster command system, which stays in contact with other subsystems via a tactical communications network. This means that Rheinmetall can integrate assets such as Skyshield or Skyguard fire units, guided missile launchers or even high-energy laser (HEL) effectors into the system. The Skynex configuration on show at IDEX 2017 features a Skyshield sensor unit, the Oerlikon Revolver Gun Mk3, a Cheetah guided missile launcher and an HEL effector. Oerlikon X-TAR3D Search Radar at IDEX 2017 Remotely operated and network-capable, the Oerlikon Revolver Gun Mk3 can be equipped with tracking sensor units such as an X-band radar as well as electro-optical sensors and electronic warfare components. This assures fast, autonomous processing of externally assigned targets.Owing to its innovative warhead, the Cheetah short-range guided missile is capable of countering the RAM threat posed by low, slow and small projectiles even at short distances – as well as a wide variety of other aerial targets. The Cheetah is fired from a multiple launcher with a capacity of sixty guided missiles. Controlled from the system, several guided missiles can be launched at the same time, enabling simultaneous engagement of multiple targets at ranges of up to six kilometres.Rheinmetall’s HEL effector is a scalable, high-precision, silent weapon system, with a virtually inexhaustible supply of ammunition.Electronic warfare components and other sensors can also bolster the system’s performance against low, slow and small projectiles. Moreover, the Oerlikon Skynex can be connected via interfaces to higher echelon command levels or other air defence systems.

Northrop Grumman’s G/ATOR Successfully Completes Initial Integration TestingG/ATOR (Ground/Air Task Oriented Radar) • C4ISR February 23, 2017BALTIMORE – Feb. 23, 2017 – Northrop Grumman Corporation (NYSE: NOC) and the U.S. Marine Corps successfully completed an initial integration event (IIE) in November 2016 for the AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR) system.The three-week IIE demonstrated G/ATOR’s ground weapon locating radar (GWLR) mode’s ability to detect and track multiple types of rocket, artillery and mortar (RAM) rounds simultaneously. Over 40 different weapon scenarios were evaluated through the live fire event, and more than 700 live shots were fired, including a variety of RAM rounds. GWLR successfully tracked projectiles including volley fire between 6km and 50km, demonstrating G/ATOR’s long range capability. Volley fire capability is the ability to detect and track multiple RAM projectiles intentionally fired in very rapid sequence in an attempt to overwhelm radar capabilities.“The volley fire capability that G/ATOR demonstrated is critical on the modern battlefield, and all of the data collected during IIE indicates that GWLR can exceed the U.S. Marine Corps’ range capability, ” said Roshan Roeder, vice president, mission solutions, Northrop Grumman.“GWLR mode detects and tracks time-critical incoming threats, calculates an approximate impact point, and then tracks the threat’s trajectory back in time to estimate a firing position, allowing counterfire forces to engage rapidly,” said Roshan Roeder, vice president, mission solutions, Northrop Grumman. “The volley fire capability that G/ATOR demonstrated is critical on the modern battlefield, and all of the data collected during IIE indicates that GWLR can exceed the U.S. Marine Corps’ range capability.”The AN/TPS-80 G/ATOR system is multi-mission, performing four principal missions using the same hardware: short-range air defense, tactical air operations control, counterfire target acquisition (GWLR mode) and future air traffic control. GWLR mode adds software to the G/ATOR system to detect, track and identify RAM projectiles, both 360-degree and sector-only. The GWLR mode addresses multiple types of simultaneous threats. Adding this capability will allow G/ATOR to replace five legacy USMC radars.

IDEX 2017: Leonardo's Vulcano 155 mm guided ammunition to be tested by USNLuca Peruzzi, Abu Dhabi - IHS Jane's Navy International23 February 2017 Key Points :* The USN is to explore Vulcano munitions for compatibility with DDG 1000s* Leonardo and DRS Technologies will conduct fire trials during 2017Italy-based Leonardo has been invited by the US Navy (USN) to verify and test its Vulcano guided ammunition for potential application to the DDG 1000 MK 51 155 mm calibre Advanced Gun System (AGS), according to Gianpiero Lorandi, managing director of Leonardo's Defence Systems division.With the support of the Leonardo subsidiary DRS Technologies, based in the United States, Leonardo is expected to "conduct a two-phased fire trials campaign" after verification and testing, Lorandi told Jane's at IDEX 2017 held in Abu Dhabi. "The activities are expected to be conducted in phases in the US with compatibility tests and fire trails during the year 2017."Leonardo's Vulcano is a family of unguided ballistic extended-range (BER) and guided long-range (GLR) ammunition for 76 mm and 127 mm naval munitions and 155 mm land artillery systems. The Vulcano 127 mm ammunition enables 127/54C and 127/64 LW naval guns to meet precision NSFS requirements and long-range engagement of surface targets. The Vulcano 155 mm ammunition enables 155/52- and 155/39-calibre howitzers to extend their operative range and precision. A mission planning module enables data exchange with the fire direction centre for the management of the firing mission.The projectiles are sub-calibre with a fin-stabilised airframe compatible with standard modular charges (155 mm) without additional propulsion and loaded with insensitive munitions-compliant explosives and patented tungsten rings. The unguided BER has multirole ammunition with a multifunction programmable fuze (altimetric, impact, delayed impact, time, and self-destruction), and the GLR is enabled with canard control actuated by a global positioning system/inertial measurement unit (GPS/IMU) guidance system for navigation (gliding trajectory) and possibility of terminal guidance (pull down) with an optional semi-active laser (SAL). In the case of naval 127 mm, there is also a guided ammunition version based on an infrared (IR) seeker. Both versions (127 mm and 155 mm) are available in BER and GLR.Developed by Leonardo for the Italian MoD, the 127/155 mm family in the BER and GLR versions are to be qualified by the end of 2017. The GLR/SAL version, which involved German Diehl BGT Defence for the SAL guidance system, will be qualified by the end of 2018.

Picatinny Arsenal advances M777 extended range howitzerDaniel Wasserbly, Washington, DC - IHS Jane's Defence Weekly01 March 2017 The ER M777A2 is shown undergoing re-fire checks and preventative maintenance during testing. Source: Picatinny ArsenalPicatinny Arsenal engineers are progressing work with their M777 extended range (ER) howitzer, based on the 155 mm M777 towed artillery system, and expect to soon test the weapon with new ammunition.Test firings in November 2016 helped advance the M777ER programme that officials hope can "create an M777 howitzer that can fire out to over 70 km", Picatinny Arsenal said in a 27 February statement.Modifications added 2.4 m to the cannon, but limited the added overall system weight to 454 kg. "The total length of the tube increased the chamber volume as well as the rifling length," Picatinny said. "That, in combination with the additional increment of legacy propellant, resulted in an increase in range of several kilometres."The M777ER is part of a wider Extended Range Cannon Artillery (ERCA) project to develop technology that can extend ranges for all 155 mm artillery. It includes a XM907 cannon as well as XM1113 rocket-assisted projectile, the XM654 supercharge, an autoloader, and a new fire control system.Programme officials are to next test the M777ER to determine if it can handle "the force from the new ammunition since we would be going from a 7 km increase in range to a 40 km increase in range". If successful, those tests could lead to user evaluations or soliciting other modifications.Testing in July 2017 will use "some new prototype hardware and new ammunition to build on the confidence we got from the November  test, but isn't a complete upgrade to the system yet", David Bound, M777ER team lead, told Jane's.Then, around July 2018, Bound expects the final demonstrator will be fully upgraded with all of the army's latest hardware. "We are working towards getting this demonstrator to be as close to representative of the howitzer we would eventually qualify for fielding as we possibly can," he said.(332 of 486 words)

Picatinny engineers double range with modified M777A2 Extended Range howitzerBy Lauren Poindexter, Picatinny Arsenal Public AffairsFebruary 23, 2017PICATINNY ARSENAL, N.J. -- Picatinny Arsenal engineers have fired the newly modified M777A2 howitzer at Yuma Proving Ground, Arizona, completing the next step towards expanding the system's current firing range."We put together an integration test bed for the M777A2 Extended Range (M777ER) howitzer program, incorporating a 55 caliber cannon tube on the M777A2 towed howitzer," said Andy McFadzean a Special Project Officer at the U.S. Army Armament Research, Development and Engineering Center or ARDEC. "We shot a total of 70 rounds using the Modular Artillery Charge System (MACS), zone two to zone six, propelling charge. This test marked the first time a MACS zone 6 was fired from the M777 howitzer. Previously, the top charge fired was a MACS zone 5."The modification added six feet to the cannon while limiting the increase in overall system weight to less than 1,000 pounds. The total length of the tube increased the chamber volume as well as the rifling length. That, in combination with the additional increment of legacy propellant (MACS zone 6), resulted in an increase in range of several kilometers. "We were able to push the round harder for longer, so it goes faster and further," said David Bound, M777ER Team Lead."Think of it like a guy with a really long arm. He can hold a ball longer and throw it faster than a guy with a really short arm. So we just integrated that longer 'arm' onto the howitzer so that the same bullet could get acted on longer and quicker. That in turn means more range," said Bound."The main point of the test was to build confidence," said Bound "that's not even the best range increase we can get, but there were some doubts that we could even go that far on the system." CRAWL, WALK, RUNProject Manager Towed Artillery Systems and ARDEC are using an incremental approach to increasing the range of the M777A2 howitzer. The ultimate goal of the program is to demonstrate a maximum range of 70KM while minimizing the cost and modifications to the weapon platform.The Army's Extended Range Cannon Artillery (ERCA) program is investigating and developing technology to extend the range of the Army's 155mm self-propelled howitzer. The M777ER program is integrating the ERCA technology onto the towed howitzer platform.Initially, a non-firing, mobility platform was developed with an extended range cannon tube. The mobility trails successfully demonstrated that an M777ER howitzer could be towed behind its current prime mover with little modifications.Upon successful completion of mobility trials, a firing demonstrator was created using the current 39 caliber cannon without a muzzle brake. The 39 caliber demonstrator put similar stress on the systems structures as a 55 caliber cannon with a muzzle brake. The test results of the 39 caliber demonstrator were used to validate engineering design models for the objective extended range weapon.The latest configuration of the M777ER weapon integrated a 55 caliber cannon tube onto the weapon platform. The cannon tube was manufactured at the Army's Watervliet Arsenal. The firings at Yuma in November 2016 marked the latest success in the M777ER program.The engineers have planned additional incremental improvements with several demonstrations over the next few years. "We're not going to do all of our design work in a vacuum and show up in five years with a system the user hasn't seen before," said Bound. "The latest test at Yuma was one of those steps. Several marines and soldiers were at Yuma in November to witness the firings," said Bound. "I think they are all very happy and impressed with the fact that the M777ER did what it did so quickly and they are definitely excited to see the next step, which should be around July 2017. "We are taking a crawl, walk, run approach to keep the user involved through the whole process," said McFadzean."Too many times we do a project like this and we think we know what they [the user] want. If we have them involved throughout the process it allows us to make the system more suitable to fit their needs," said Bound.The engineers thought weight would be a limiting factor, but it was not. "It actually looks like the strength of the gun will be our limiting factor, which means we can design the M777ER to its engineering limit. Knowing the engineering limits of the system coupled with input from the user will allow designers to optimize the objective system," said Bound. "The latest test is certainly an intermediate step. We saw a few different outcomes then we expected to see. For example, the gun is very light so it moves when it shoots especially at low angles but we did not expect to see it move as much as it did. That wasn't even on our radar as an outcome of the test. One thing we expected to see and didn't was an increase in tube whip, the bouncing of the cannon tube after firing, but it appears the elevation system can lift all that additional weight and still hold the tube steady," said Bound.BLAST OVER PRESSURE"Another concern we are dealing with is the blast over pressure," said McFadzean."When the weapon is fired, it's like setting off a very large firecracker. There is a blast wave that comes out of the muzzle. The muzzle brake, which is located at the end of the cannon tube, takes that energy of the extra propellant gases and redirects them backward so that it helps slow down the tube during recoil," said Bound. "Think of it like a sail on the end of the cannon tube that's catching all of that blast to slow the gun down.""Unfortunately, this redirects all that energy back at the crew and, if we redirect it too much, we hit the crew with a large blast wave that can hurt them. To reduce the impact on the crew, the engineers at Benet Laboratories are designing a muzzle brake that gets us the efficiency we require while keeping the crew safe and out of the way of all the redirected energy," said Bound."Testing to date has been done with legacy ammunition which is what the soldiers and marines currently use every day. ERCA is also designing a new rocket assistant projectile and a new super charge," Bound added."The next step is to see if the M777ER platform can take the force from the new ammunition since we would be going from a 7 kilometer increase in range to a 40 km increase in range. Once we prove that we can actually do this, a user evaluation will be conducted and feedback on any other modifications will be solicited. This can be expected around July of fiscal year 18," said Bound.The M777ER program is a collaborative effort between PEO Ammunition, PM TAS and ARDEC. ARDEC's role is to provide the engineering to push the system to its limit to maximize range. The job of Program Manager Towed Artillery Systems is to work with the Soldiers, Marines and ARDEC to refine the systems requirement to make sure user expectations are met.-----The U.S. Army Armament Research, Development and Engineering Center is part of the U.S. Army Research, Development and Engineering Command, which has the mission to ensure decisive overmatch for unified land operations to empower the Army, the joint warfighter and our nation.
