Terrorism is the Gulf? You think not spending about £30 million on a sensor that tells you what is happening beneath the vast expanse that surrounds a ship is justified because terrorism in the Gulf? Do you think the Gulf states don’t have assets of their own to deal with terrorism. Your comment is so shortsighted and skewed and frankly bizarre I honestly don’t know where to start to address it. If any ASW sonar, add CAPTAS-4 and make T31 the 2nd-rate ASW escort. For T31, mine-avoidance sonar is the most we need. I would rather invest the resources to ARCIMS SeaSense ASW USV, and/or SeaGuadian MQ-9B ASW-USV. And, still, SSK location is known = they are almost dead.ĭo we really need a hull sonar on T31? Hull sonar will never make her an ASW escort (not even 2nd-rate). SSK might shoot a torpedo, but torpedo countermeasure can do all what they want. As hull-sonar is so inferior to modern SSK, SSK will be located very near to T31, and torpedo countermeasure may not have enough time to react.Īnd, if there are P-8As and Merlins in the sky, why not they themselves ping?Ģ: Pinging a CAPTAS-4 will detect SSKs from large distance (as described as “quantum leap”). SSK may not shoot a torpedo, if there is an air-cover, such as Merlin and P-8A which will come to sink it if T31 had been sunk. CAPTAS-like sonar is more important, but is hull sonar so?ġ: Pinging a hull sonar is equivalent to saying “please shoot a torpedo to me” to the enemy sub. This mean, hull sonar is “quantum leap-level inferior” to CAPTAS-4 or alike. Nothing to do with “requirements” per se.īefore we all prostrate ourselves at the altar of the T31 as the “new” way, we might want to wonder whether – for example – a 20 year old design has all the growth margin the RN want……Ġ: In ALL ASW related reports, low-frequency active-passive VDS+TASS systems is stated as “quantum leap in capability” against hull sonars. Long stand-off over who would pay, compounded by trying to hide the size of the thing (in displacement terms) and a comedy build schedule and price. Unfortunately, a major design change was required and because they’d done too much detail too early, there was no money left to do that revision.
