I was flipping through an old issue (2004) of Armada International which has an article on naval radars.

In this article, it says that each APAR antenna unit weighs some 8 tons and SEAPAR would allow a reduction of ~ 50% in masthead weight (meaning ~4 tons per antenna unit).

Though I understand antenna weight is just one parameter among others, I hadn't realized APAR was

I haven't checked any other source on the question, but do these antenna weights for APAR/SEAPAR sound correct to our informed audience ?

Assuming the weight given for SEAPAR antennas is correct (i.e. 4 tons per face x 4 faces = 16 tons), is it really possible to fit it on warships as small as 1,500 tons like it says in the Armada article ?

Thanks in advance.

Regards.

Matt.

*so**heavy*, with a weight per antenna about twice that of SPY-1D (if the figures from Armada are correct).I haven't checked any other source on the question, but do these antenna weights for APAR/SEAPAR sound correct to our informed audience ?

__Edit__: APAR data from Norman Friedman's*World Naval Weapon Systems*, 2006 Edition, page 266 :Total weight is 20 metric tons, half of it topside (2 metric tons per array). Heat load per face is 85 kW; the arrays are liquid-cooled.
