Late 80s (88-90) US Navy Program to replace the E-3C, S-3B and EA-6B carrier-based AEW, ASW and EW aircraft. I believe it evolved into the E-X program to replace the E-2, this is why i’m attaching the image of the Boeing E-X proposal, which is seen here in ASW markings. (VS-24 scouts was an S-3...

Since there aren't any large threads for FREMM already, I figured I would create one specifically to discuss the background and development of the FREMM-EVO, a pair of interim frigates ordered for the Marina Militare Italiana. Background: Before we talk about the FREMM-EVO, we should talk...

The saga of the Royal Navy's carriers after 1966 has been the main focus of interest here, but the workhorse of the RN then as now was the frigate. By the 1970s the RN had plans to replace its Type 12 Leander class frigates with the larger all missile armed Type 22. Leanders were designed...

LCAW was a NATO program for an small torpedo, cheap/expendable enough to be use against unidentified/unverified sonar contacts. It was supposed to have both rocket-launched and helicopter-dropped version. At first it was a trilateral US, German Norwegian project, but some point ~1990 The US...

Saw this in an article as I was looking for some information on the Reformers of the 1970s-1980s: "Hart and Lind have long made public their dismay with America's supercarriers, which, they argue at length, are vulnerable, too expensive to deploy in the numbers needed, and carry the wrong kind...

The Ministry of Defence has awarded a £60 million contract to Leonardo to design and develop a 3-tonne helicopter UAV demonstrator. One of trials will be to drop sonobouys from the UAV. First flight is due in 2025...

Does 3"/70 (7.62 cm) Mark 37 have the potential to shoot at the sea. Just like British 3"/70 (7.62 cm) Mark VI？ DL1 NOFORK known as a destoryer killer（ddk）and it has four mountings of this type，but i can't find any ammo about this gun that can attack sea target. so how NOFORK anti ships？

ABC News: "Hunter class frigates will be built by BAE in Australia — but what can the warships do and why do we need them?" http://www.abc.net.au/news/2018-06-29/hunter-frigate-build-bae-what-you-need-to-know/9923912

I came across the Saro P.200 brochure at Kew and a file of related correspondence. The P.200 was designed in 1957 to meet an Admiralty requirement. The hull was a normal planing bow with a tunnel aft to carry a Pentane A/S homing torpedo. The hydrofoils and rudders were separated to allow the...

Hello everybody! I always found the various proposals for the USN "Type" A V/STOL competition fascinating and the Boeing Model 1041-133 in particular. In my opinion the Model 1041-133 with its mechanical driven lift- and cruise fans and variable pitch control system was (and still is) the most...

Hi, here is an ASW V/STOL seaplane project,from DTIC report,but I just ask if that aircraft related to General Dynamics or not,that is because this article in the report; 11. Dewey, D. B. Full-Scale Demonstration of the Vertical Float Sea-Stabilization Concept. San Diego, Oct 1963. 25 p...

As stated in the companion thread on the Grumman G-132 design, "The 1955 CNO OR AS-040502 required an ASW flying boat with the ability to alight in the open sea, up to sea state 5, in order to operate a sophisticated dunking sonar, AN/ASQ6." This resulted in the "Open Ocean Seaplane" request for...

Found a couple of notes on Invincible class from my Aviation & Marine International magazine collection September 1979: April 1976:
