In the fist video, why is her bow hook (anchor) down in the shots she is being nudged out into the channel? Or is it no longer ( the chain) attached to the
anchor, seemed like it had some tension on it though.

In the fist video, why is her bow hook (anchor) down in the shots she is being nudged out into the channel? Its where they hook up the tow line for the ocean tow, the ocean going tug is to the right. It looks like one of the USNS Apache class ocean going tugs. They would use chain for the connection to the ship because of the danger of chaffing, while the rest of the towline is steel cable When actually towing at sea most of the towline is dipped underwater. This dip acts as a shock absorber to take up the strain of both ships going in slightly different directions. At sea its actually the weight of the towline that pulls the towed ship forward. If you tried to directly pull the ship and keep the towline taught at sea it would either break the towline or rip the fittings out of one or both ships as soon as they were on different waves. |

I assumed it wasnt the hook, I know she was the only CV with a bow hook right under the bow as she also was the only one if I recall with bow mounted sonar,
that right? Weird, a carrier with sonar....

No she was not the only one with a bow sonor, USS Interpid has one, and so did USS Oriskany.

SCB-144
SCB-144 was part of the Navy Fleet Rehabilitation and Modernization (FRAM) II program intended to improve the ASW capability of the SCB-27A CVS carriers. All of the SCB-144 modernizations were completed by 1965. The principal modifications included: 1. Installation of the SQS-23 bow-mounted sonar dome. 2. Installation of a stem hawsepipe and bow anchor. 3. Modifications to the Combat Information Center. Ships which received this are: CVS-9 Essex, CVS-10 Yorktown, CVS-11 Intrepid CVS-12 Hornet, CVS-15 Randolph, CVS-18 Wasp, CVS-20 Bennington, CVS-33 Kearsarge |

Not really. Many carriers, primary CVS, had sonar. As did other deep draft ships, primarily CLG and CG, in the Cold war. And it was planned but never
implemented in AOEs.
Why, you may ask? In the context of cold war ASW and task group operations, deep draft sonar was frequently below the layer (run that term in google in conjunction with sonar). This was useful for the same reason variable depth sonar was useful. Although the carriers did not carry ASW weapons, they could acquire and maintain sonar contact with submarines that DD-types could not. Thus, the ship in contact could coach the ship with the weapons. A related ASW business was 'Vectacs" where a DD in contact vectored in a VP aircraft (not in contact) to drop on a submarine outside the DD's weapons envelope. |
