spooning is big with them!

What SURTASS LFA works (as an active sonar) is different from a dipping active sonar.
One way to do a dipping Active Sonar is to use a blimp (as in the Goodyear Blimp).
SURTASS must go at slow speeds to find stuff...
A Blimp might be able to go up to 40+ knots and then maintain a position to dip the sonar.
In point of fact, blimps were used in WWII to find German/Japanese Submarines (though mainly German U-boats).
Currently platforms that may provide Active Dipping Sonar are limited by weight and time over the area to hunt the sub... (Helicopters or V-22 Osprey).

There are dipping passive sonars... These are airborne systems... (At least to my knowledge)

So you were on SURTASS ships also? When I was on them, there was not enough room to house more than a couple extra bodies. If they have reduced the crew size to accomodate a security detachment, why don’t they have them?

Yes I know, but these ships are not designed to dip sonar, LFA is the closest they have.

I worked on a project under TACTAS. It was a project attached to a Surface towed array system like SURTASS LFA, but it was only passive.
They added the ability to have a "dipping sonar", but that was only a passive system.
This was at the time SDI or STAR WARS was bounced about...
Fast forward about 30 years and you have SURTASS and other systems...

Also, these days, an MSC-operated vessel can get a USCG waiver to carry a SecDet above and beyond the COI limit.

I’ve heard of TACTAS a long time ago. I got started with the SURTASS program in ‘84.
