Ambassador III class

The Ambassador III class Supply Cruiser is a variant of the Ambassador class deep space exploratory vessel utilised by Starfleet.

Background
The Ambassador III class have been modified from out of decommissioned space frames of Ambassador class Heavy Cruiser. By the 2360's the mission role of the Ambassador became more and more limited to the role of border patrol and defensive specialist with fewer and fewer assigned to deep space exploration and diplomatic transport. Continued refits kept the majority of the Ambassador class starships in service, despite the end of their active production run.

Description
Ambassador III class Supply Cruisers were commissioned beginning 2370 to serve primarily as supply cruisers or military freighters to provide repair parts, consumables storage, and other logistical needs. They are thus equipped with advanced cryogenic deuterium drives and are armed with modern force recoupling phasers.

The modified Ambassador III ships are essentially interstellar cargo carriers, with a top speed of warp 9.5, only 12 decks for its crew, and 28 huge cargo holds of various sizes. But due to the combat-intensive nature of the period these ships were assigned to, much of their armament have remained unaltered.
