I dunno if I'd take that statement too seriously. As a strategic
countermeasure to the Soviet Navy's overwhelming number of subs at the
time, they were designed to deliver nuclear depth charges with a
possibility of surviving. The InSurv board had quite a lot to say on
the matter.

During sea trials they were shock tested with 4,000 lbs (4 kT) of explosive:

The ASROC had a 10,000 lb (10 kT) yield:

'scuse me,,, 10,000 lb is 5 T, 10 kT is 20,000,000 lbs, small difference.
