No, that is totally different. Its the nature of the beast, air power is very quick and sporadic, sea power is slow and persistent. There may be under a minute between detecting a threat and taking a hit, whereas engagement with subs tend to last hours.
Negative. If you think ASW Merlin is always there, in AAW-wise, AEW asset will always be there coupled with a few F35B in the air for CAP, and there will be no such case as "under a minute between detecting a threat and taking a hit" in AAW.
But no, there will be a situation AEW is not working, as well as a situation ASW Merlin is not flying enough.
Assuming getting ambushed and seeing sudden attack = detecting enemy sub only after detecting the torpedo is very likely, much more than getting a sudden attack in air raids. On the other hand, as underwater sensor is very difficult (the reason why frigates see difficulty on finding enemy subs), torpedo itself will find it difficult to detect our frigate from long distance because its sonar is very small (compared to sub's TASS). So, wired guidance is critically important when attacked from a distance.
For example, if the sub is 20 km away, it takes 12 minutes for a 50 knot high-speed heavy torpedo to reach us. The frigate shall fire ASROC to the sub, forcing it to cut the wire within 1-2 minutes. Still the torpedo is at 18-19 km away. Then, the frigate can perform good anti-torpedo soft-kill maneuvers. Of course, the torpedo cannot continuously swim at 50knot, because the noise will completely disable its sensor. Without mother-ships' wire guidance, the torpedo needs to slow-down and "listen", giving another several minutes to our frigate. I think this is not "specific" case, but rather a typical case of reaction to sudden attack/ambush.
Without such reaction, T26 will be forced to handle heavy weight torpedo in highest speed, wire-guided until just before the hit.
To be clear, I am not suggesting ASROC is useless, I'm suggesting it's not the no brainier like some here have proposed.
Here I totally agree. For me, it looks as if RN is still thinking the golden era of ASW is there, that the frigate is the hunter and SSK/SSN is the game, which was possible in 1990s. But now, again, frigates are the game and SSK/SSN is the hunter, I understand, so expecting ambush and sudden attack shall be very reasonable.
On LWT, I guess RN is thinking ship-torpedo-defence (soft kill) is much more important to invest than putting almost useless stingrays onboard. This idea itself is reasonable.
PS By the way, ASROC warhead is already Mk.54, from 2010 on. So, there is no "logistic issue", if P8A carries Mk.54.
