A contemporary of the Federation Scorpio Corvette, the Sehin Morlatta is a cheaper alternative to the larger bird of prey-type vessels employed by the Romulan Star Empire during the period. Flotillas of Sehin Morlatta Corvettes could be maintained for less and were thus built in large numbers.
These corvettes were often used to raid neighboring low-tech worlds in the neutral zone. These attacks served as field-tests for advances in cloaking technology be developed by the Empire.
The Sehin Morlatta saw its most intensive service along the Romulan/Gorn border. Heightened tensions during the late 23rd Century led to a continuing series of border raids by both parties. Expandable corvettes were a weapon of choice for the Romulans whose larger battlecruisers were deployed instead along the Federation and Klingon borders.
The Sehin Morlatta is named for an insect native to Gorwah with a poisonous sting that is particularly nasty to the Gorwah but fatal to Romulans, who call it sehin morlatta or "stinger of death".
