LO: noted.
The weapons system (as with most things, part of a life cycle acquisition process) will get revisions and fixes throughout its life. I seem to recall a problem with the first or second F-14 in hydraulics, which lost the plane. For a long time the engines were subject to stall at high angles of attack during certain high demand maneuvers.
Did that make the aircraft NOT ready to deploy?
No.
When the F-14 finally got the better engines (and as some put it, the engines they should have had in the first place) that problem went away, but it had already been providing fine service before that.
I do appreciate the software issue being a potential show stopper. I am modestly familiar with CH-60 (now MH-60S) comms short comings early in its life, familiar with SH-60 block upgrades, and slightly familiar the weapons systems delays for AH-1Z. (Systems integration issues).
Each had a different impact on schedule and deployment, for sure.
