anti-submarine warfare

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...

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?

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...

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)...

Whenever I look at my little model of the USS Long Beach nuclear missile cruiser I find myself musing what a 21st Century version for Western navies could look like? Such a ship would replace the Ticonderoga class in the US Navy and perhaps provide Task Force escorts for the RN and MN instead...

Something different for today ... a collaborative project between Grumman and Shin Meiwa in Japan. Note wing engines can tilt up a few degrees (it's described on another page). Also, there is heavy reliance on active boundary layer control via twin turbines behind the rear pressure bulkhead...

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

Some time ago, we managed (thanks to JFC Fuller) to get some decent info on the proposed 1962 Royal navy Escort Cruiser https://www.secretprojects.co.uk/forum/index.php/topic,1600.msg184219.html#msg184219 Unfortunately as so often the thread go sidelined into discussions on launcher...

1983, rather than 1982 is a key date for decisions for the RN and UK defence as a whole, in the light of the Falklands and it's effect not just on defence thinking but on the UK populace's attitude to their country. As surely as it was to the political establishment. But in terms of changes a...
