Paperplane is correct.
There is a reason why the large ASW exercises NATO does every year are British in design, and it is no accident almost all of the exercise instructors
and specialists are Canadian, French, and British. The intensity of the British ASW training and war games are legandary in Navy circles.
That isn't to say the rest of Europe is bad or anything of the sort, most of Europe has been well ahead of the US in ASW for at least over a decade,
but the clear NATO leaders in ASW training has been Canada and the UK, and the leaders in ASW technology for most of the last part of the 20th century
Many independent Canadian, British, and Australian experts have noted that the amount of effort and money the USN is putting into ASW training,
exercises, and technology is changing ASW as it is currently known. The US Navy is among the leaders in UUV and USV technologies through its wide
array of partnerships worldwide, and made creative use of these technologies in changing how ASW will be conducted in the future.
One example is the Spartan USV, which is a cooperation between the US Navy, Royal Singapore Navy, and the French Navy.
The Spartan USV gets real world testing in the Perisan Gulf operating from the RSS Endeavour, currently assigned to the northern Persian Gulf
protecting the Iraqi oil terminals. Most people don't even realize Singapore is supporting the Iraq war, or that the French Navy has observers
onboard, but real world testing in Iraq is common for these emerging technologies.
In the LCS model, for ASW warfare 2 Spartans will independently deploy towed sonar arrays for sprint-drift capability, or perform stration-keep sonar
capability working as a data-relay echo reciever for USVs performing echo scans.
Interestingly enough, in the SUW module for the LCS, the Spartan USV is being designed to carry the NETFIRES missile system or a 30mm gun, which when
combined with the infrared imager and a laser rangefinder / designator, synthetic aperture/moving target indicator radar, and Tactical Common Datalink
(TCDL) Terminal makes the Spartan USV a nasty stealth USV able to guide anything from D-GPS munitions to LGBs with real-time BDA.
The Spartan USV is just one example of many unmanned systems the US Navy is involved in with partnerships with other nations as they change focus and
improve their ASW capability. So far, the nice side effect has been enormous capability increases in both mine warfare and anti-surface warfare, 2
other areas the US Navy also needs improvement.
