Follow up:
Those sub AAM systems were not operational at the time of TWA800.
Interesting. For the archive:

Summary: USS Knox was positioned off of Wallops Island and shot a missile, which destroyed TWA800. The USS Normandy was 180 miles away using its computing power for intercept point and monitoring the test. It was an accident that has been covered up.
Before something becomes 'operational' and in 'production', it has to be created and tested.
Why couldn't this have been something NEW that they were TESTING ?
What is interesting is that after the TWA800 incident, the testing of experimental new AAM systems for subs was halted for many years.
