2245

Historical Events

• The Ariadne patrol corvette class (and its subclasses) starts receiving a weapons upgrade.

• USS Troy (NCC-423, Siva sub-class) and USS Hellas (NCC-426, same) succumb to Klingon forces at Delta Leonis.

Probably prior to the Final Battle of Axanar. The two names are acquired for the Loknar class.

• The last of eight Aldrin sub-class deep space frigates are refit to Magellan sub-class scout cruiser standards.

• The Detroyat class heavy cruiser receives a transporter upgrade.

• Pre-comm Ares (NCC-602, Monoceros class) is damaged beyond salvage during the final construction phase, in what appears to be an accident.

This was later revealed to have been just one of several Romulan acts of sabotage on starship construction that year.

• The last Hermes sub-class scout is converted to Monoceros standard.

• The final Monoceros sub-class newbuild is completed.

• This year's defense review seals the fate of numerous pre-dilithium ship types.

• April 11: USS Enterprise (NCC-1701, Constitution class) is commissioned, with program manager CAPT Robert April in command. USS Constitution (NCC-1700) is commissioned shortly after.

The order of commissioning is not clear in Timo (though it does say they "were held almost concurrently"), but I recall that there was a factoid that the Big E came before the Connie.

• May: USS Republic (NCC-1371, Constitution class) is re-commissioned.

The year is conjecture, based upon her re-assignment to training duty in 2248.

• June: USS Constellation (NCC-1017, Constitution class) is re-commissioned.

The year is conjecture. It is presumed she was commissioned after Republic due to the less extensive modifications to the sister ship.

• September: Final Battle of Axanar, where the "battered" USS Constitution and three of her "half-finished" sisters are moved to the forward repair base in orbit of the planet as a lure.
