anti-submarine warfare

A few days ago I stumbled across this ASROC training video from Periscope Films and I was surprised when I checked the board that no specific thread for the ASROC has been posted so hear goes: Now for some stats from the RUR-5 ASROC wikipedia page: Detonation of W44 warhead launched by an...

Perhaps the most ambitious NATO programme of the 1980s was an attempt to design a common escort ship platform for NATO navies: NATO Frigate 90. https://www.secretprojects.co.uk/threads/nfr-90-and-other-pre-horizon-aaw-projects.923/ The project foundered as it became too expensive and failed to...

An article about the Irish having to call the RN to scare a Russian sub away from its territorial waters last summer, and thought a sub chaser would be able to solve that problem…but sensors and weapons for ASW have come a long way, and can a ship be built small and cheap enough to really mimic...

Briefly mentioned here, I remember stumbling across this system on another, now defunct, website covering US sea mines. If I remember, the project dated from the 1970s, and included two variants of rising mine, one based upon a small torpedo, the other rocket-propelled.

I was curious to see if there had been any drawings of this paper ship plan. Basically a anti sub/ trade lane protector ship for th usn, 20 s-3 in 2 squadrons plus 4-8 small anti snuper aircraft (presumably a-4 but no design specified) and 16 sea kings, to be biult in the 70's to replace the...

Been trying to find out more on this subject, but there seems to be frustratingly little. I'm interested in finding out data on 1970s-1980s soviet and american radar processors to form an idea about the oft-mentioned gap between the two in this domain. i'm not a computer man so anything detailed...

A few months ago, I posted a thread on a briefing with several more or less obscure frigate concepts for the USN. One of the designs included in that brief is the PXM, which I described at the time as a rabbit hole. This thread is my attempt to chase that rabbit as far as I can go, starting from...

This alt obviously requires a bigger UK Defence budget but 8 County class ships were in service by the early 70s. Replacing the forward 4.5" guns with one or two Mk8 or Exocet (later Harpoon) and one Mk8 should be relatively easy. The Seadart mounting on Bristol T82 could have been adapted to...

It is well known that apart from HMS Bristol no RN ships equipped with Ikara deployed to the Falklands in 1982. I have two questions arising from this. Did the RN consider and reject sending Ikara Leanders south? Did Bristol use its Ikara against Argentine subs?

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 saga of HMS Hermes is well known. But it might have been different if the RN had followed the US example and kept her as an ASW carrier or interim Sea Control Ship. The US were introducing the S3 Viking on to their attack carriers but were keen to get as many to sea as possible. HMS Hermes...

Rather than aircraft carriers I think it is US nuclear submarines that pose the main threat to Chinese seapower, so I was interested in this article: https://nationalinterest.org/blog/reboot/china-improving-its-anti-submarine-warfare-capabilities-197071 The Western powers have been in the ASW...

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...

White there is information about the missile itself: https://www.designation-systems.net/dusrm/m-84.html https://www.docdroid.com/WbANE9i/agm-84-harpoon-missile-block-1d-brochure-pdf#page=2 There are mentions that, one of the reason it wasn't produced, was that the missiles were too big for...

Wiki has quite a good summary of the abortive attempt in the 1980s to design a common escort ship for NATO navies https://en.m.wikipedia.org/wiki/NFR-90 The thread about the Kidds for the RN reminded me of this programme. It ought to have been possible to design a ship flexible enough to...

A friend of mine has asked me to check out a rumour that HMS Cockade sank a suspected Soviet sub while serving with a US force in the Korean War. He thinks the papers are embargoed until at least 2050.

Didn't really see a thread on this so here we go! I guess its not so popular because only Canada operates it.. but why they chose this instead of more Merlins is beyond me... 82% grounded due to cracks :eek...

Navweaps (which I’m sure we’re all familiar with) lists something called the Mk-47 torpedo. It says the program was terminated in favor the Mk 48, so it probably ended sometime around the Mk 48 began development (1970). Furthermore, my 14th Edition of Ships and Aircraft of the US Fleet (1986)...
