The ST-70 class M-111 Assault Ship, colloquially known as a Razor Crest, was one of several shuttles designed by the Galactic Republic in the final stages of the Clone Wars. Like the Theta-class and the Omicron-class, the ST-70 was intended to be a successor of the popular LAAT and Nu-class shuttles used by the Republic’s armed forces. Shipwrights envisioned the ST-70 as the perfect patrol craft, and they designed the specialized shuttle to serve the needs of law enforcement and planetary security. It was significantly larger than its predecessor but only required one pilot. Despite its size, its passenger capacity was decreased to allow for a larger cargo bay, advanced sensor equipment, and modular facilities to safely transport prisoners.

Its two powerful Turbodyne engine turbines sit at the end of short wings that extend from the dorsal side of the shuttle, increasing its efficiency in atmospheric flight. These engines make it one of the faster non-military ships of its class. The ST-70 keeps its predecessor's popular armored sliding doors, but the shuttle’s designers shrank them in proportion to the fuselage size to provide the passengers more protection. Because the Razor Crest was designed for civilians serving far from active warzones, the standard models came only with two fixed-direction heavy laser cannons that sat on either side of the slim cockpit and reduced armor plating. The budget that was saved on weaponry and armor was invested into a state-of-the-art sensor package, which is still much sought after even more than two decades after its release.

The ST-70 never saw widespread mass production for several reasons. First, as a ship designed for civilian agencies, it was never officially adopted by the Galactic Empire who controlled the majority of the former Republic’s production facilities after the war. Secondly, the growing popularity of the new Lambda and Sentinel shuttles within the Empire meant more LAAT and Nu-class shuttles were sold as surplus to civilian governments, who preferred them to stripped-down models like the ST-70. While it was never successful in its intended market, the Razor Crest has found its niche in more recent years with bounty hunters who took advantage of its detainment facilities and sensor strength to aid in their work around the galaxy.
