Challenger-Class

The ships are powered by hydrogen thrusters and a nuclear reactor. The interior consisted of several levels, but the bridge was on the bottom level and had limited visibility, as it was protected by a barrier of armor. However, a direct laser shot to the bridge or engine room would effectively cripple the ship, as seen during the Battle of Icarus with the TSS Liberty, which was sent to escort Admiral Jackson tactical team to the Black Vault research site and was destroyed by a Shcnavic Imperial Navy Dreadnoughts four Atlas Lasers.
