Lonsigar

Lonsigar was a commodity. During the Galactic Civil War, a supply of lonsigar was abandoned in an asteroid field, and later recovered by a Rebel task force led by the Mon Calamari Star Cruiser Stimsenj'kat. A pair of Strike-class medium cruisers in service around 3 ABY were named Lonsigar 1 and Lonsigar 2.

Behind the scenes
The name appears to be a play on the term long cigar.
