Columbia

The IMC Columbia was an Osiris Class Heavy Destroyer, she was considered state of the art, and designed to wage war against a threat that had evolved to combat the IMC with their own custom vessels.

Construction and Launch
The Columbia was the third of the Osiris Destroyers to be laid down and launched, comissioned by the Navy, she was sponsored by the Columbia and Challenger Memorial Group which had been remembering the crew lost on the earliest space disasters in human history. Her sistership Challenger was comissioned four years earlier and was the third ship to bare the name Challenger, while Columbia was the third as well, both their predecesors were Liberty Class Escourts which had been decomissioned.

The Columbia was the "black sheep" out of the batch of Osiris Destroyers, being heavily modeled to be an affordable ship, however during her construction and the loss of the Andromeda the Challenger was recalled and refitted with new additions to make it safer, it would delay her construction by two years and thus was clasified as a revision B ship.

Unlike her sister ships which used a honey comb design the ship had cut corners using a cross beam design to reinforce her hull, which would make her unusually weak for heavy bombardment, it also was the first ship to fully utilize a fully integrated computer system, allowing it to nearly be controlled all from the bridge.

After her completion on March 22, 2539 she was launched and under went her trials. She was commisioned and named Columbia on March 30, 2539, she was chistened by Admiral Mercer.

Known History
The Colubmia early in her history would run through three planetary defense campaigns, including the Inverness System ironically fighting next to her incomplete sister ship the Yuri Gargarin and it ironically would be destroyed before it's completion. She would sustain heavy damages and entered into dry dock for repairs.

Destruction
In 2550 the Colubmia would participate in the Battle of the Rogue Star, in a disasterous failure, she would be heavily damaged beyond repair, her Commander failed to follow retreat orders, leaving her second in command to issue general order 13 to evacuate her. Her Commander remained behind to scuttle her.
