Davis-class patrol boat

The Davis class patrol boats are a six-boat class of patrol gunboats, operated by the Texas Department of Public Safety Texas Highway Patrol Division for patrolling the Rio Grande. Each boat has an armament of five FN M240 7.62 mm machine guns, and is powered by three 300 hp outboard engines.

Officially classified as "shallow water interceptors" and operated by the Highway Patrol Marine Unit, the boats of the class are named after officers of the Texas Highway Patrol who were killed in the line of duty. The first boat of the class is named J.D. Davis, the second, D.I. Rucker; the remainder of the class has yet to be named.
