MarsGuard Hancock Class Heavy Patrolboat Class History Hancock class ships were originally BA Heavy Gunboats. The BA sold these older, pre-pulse refit ships to Mars at a discount, and Mars refit them for orbital use. The forward blast cannons were replaced with railguns, and the interceptors with dual unipulse cannon turrets. The side blast cannons were replaced with dual particle beams, and the hangar was increased in size to accomodate a third shutle sized vessel, usually an Enforcer. The first ship left dock in December 2262. A total of five heavy gunboats entered MarsGuard service. Hancock Class SCS
