How do you know that we didn't develop something that would make Seawolf obsolete?

...only that the Virginia-class attack subs have been variously described as scaled-back Seawolfs (Seawolves? That's kinda like Toronto Maple Leafs, isn't it?) That doesn't suggest that there was a black program, only that the Navy couldn't afford the Seawolf-class SSN's.

OTOH, the original M1 Main Battle Tank was also described as a cheaper MBT-70. It's much more than that now.

There are dozens, if not hundreds of weapon systems that the general public and even large sections of the active military know nothing about.

Even the U-2 and SR-71 platforms were run by the CIA for a long period of time, with a few very select members of the military knowing anything about their existence.
