Project history: Small ships intended for coastal patrol service. Both 76mm guns were placed on a forecastle.
Modernizations: 1946, all (as rearmed in the RIM service): were armed with 1 x 1 - 76/40 HA/LA Mk IX, 1 x 1 - 20/70 Mk III
Naval service: Chahrokh and Simorgh 25.8.1941 were captured by boarding groups from Australian sloop Yarra at Khorramshahr, Chahbaaz and Karkass this day were captured by boarding groups from Indian sloop Lawrence at Bandar-Shapur.
