The MTB-1(1) is a British motor torpedo boat. It was introduced in Update 1.83 "Masters of the Sea" as part of the British fleet closed beta test. With the split of the naval tech trees in Update "New Power", MTB-1(1) was moved to the coastal fleet tech tree where it is now the reserve vehicle.

Decently fast and manoeuvrable, the MTB-1(1) is the reserve vehicle of the British coastal fleet tech tree. It carries a pair of torpedoes and sports a large number of guns, eight 7.72 mm Lewis 1916 machine guns in total. However, each machine gun individually has a poor damage output and a low effective range, so combined with her low survivability, extra caution is needed to fully utilize the MTB-1(1).

There is a premium version of this vehicle, 2 series(uk_mtb_2series), which differs in the gun mount placement and number of depth charges.
