Star Trek Online's newest starship is Oslo sleek and dangerous

Massively:

"Designed in the 2390's (around 14 years before the game's stardate, 2409) the Oslo class is one of the earlier heavily modular ships pushed for by Starfleet Corps of Engineers after the Dominion wars. Thus, the Oslo was based on the Norway class, although shares many components with the Akira and Zephyr classes. By emphasizing on this type of design, an Oslo class starship crew is capable of rapid field repairs after battle using generally whatever components they have on hand."
