Sorry, but what's a Typhoon?
Anyway, I agree that some things may be out of date, and the fact that the Colossus took 20 years to build probably meant that it had to undergo a lot of refits and stuff.
However, I do not agree that the Mjolnir may be added to every ship in the fleet. Mjolnirs are only seen in ONE mission in the game, and only in small numbers. I think they would be exceedingly expensive, and every single one might need its own reactor (VERY likely since they're not connected to anything anyway). Retrofitting a ship with a load of Mjolnirs without independent reactors may cause stress on the ships reactor, and it's probably not feasible to add 20+ extra reactors on a ship.
Maybe in 20 or so years, but not in 5 years.
