Through Deck Spruance Class

It's not signed, and looks like it is probably the product of more than two people. It's 70+ pages including some CONOPS ideas, selected structural diagrams, stability curves and ship motion sea state polars, etc. It's clearly a fairly well worked out design at this stage, not just a sketch.

Looking again, it's pretty close to the first Shipbucket drawing here. The main difference is a detail about a proposed quiet/low-speed drive system (basically a big outboard) and some details about the Sea Sparrow launchers (which are not really shown in the overhead drawing -- there's a set somewhere along the starboard deck edge as well as to port.) The CIWS guns are specifically EX-83 (not yet Goalkeeper).

[/color]SM-5 was a once classified program to remotely designate targets for semi active Standard Missiles. It was tested by placing some navy radar on top of a mountain in Hawaii, but ultimately not proceeded with in favor of SM-6 using an AMRAAM seeker. The reason the USN wanted this concept was that semi active guidance is much harder for the enemy to jam because of the higher power levels involved, and it offers positive control over the missile in complex air situations when friendly and neutrals mix with hostiles. Active guided missiles always present some risk that they’ll acquire the wrong target, though the two way data link on the latest AIM-120D will reduce that risk. SM-5 would also have made over the horizon anti ship attacks possible using the multi mach speed and very long range of Standard ER which is a very handy feature.
[/color]I’ve read that in the end SM-6 was said to be 80% of the capability for about half the cost, because expensive modified fighters or AEW plane with high power illuminator radar capability would not be required. It appears that both podded illuminator systems and dedicated illuminator planes were being considered. Instead SM-6 just requires some added features to the E-2D Hawkeye which was going to be built anyway, so it can supply mid course guidance commands. So that’s why SM-5 fell by the obscure wayside and SM-6 is now in production. However it does mean each SM-6 warshot costs more then an SM-5 warshot would have; but it would take a very large number of production SM-6 missiles to make up the difference in total program cost.

FYI that whole site got a revamp years ago that broke prior links but the content still exists and more. Also they now consider prior technical digest articles to be archived. You can find all the volumes below.
