Initially, The Narwhal mk1 (above) was designed by 51Peg Corp as a high-end civilian interplanetary ship. But her speed and low radar signature has been noticed by the military. The weaponized version is consequently used as solar systems patroller or long-range scout. The mk2 (below) larger is equipped with a more powerful ion engine (thrust-to-weight ratio reachs 10 !)and various missiles may be fitted in the mid section bay.
