The Allied (Soviet-British) military intervention in the summer of 1941, resulted in the Iranian navy being somewhat reduced. The info below should make the reader more familiar with how, and in what manner, this "down-sizing" was carried out.

Crafts:

Shahbaaz Class (1932, 331 tonnes; 51.8m/6.7m/1.8m; 15 knots; 2*76mm, 2*37mm).

"Shahbaaz" - captured in August of 1941, by Royal Indian Navy (RIN). It was incorporated into RIN's fleet under the new name of "Hira". Returned to Iran in 1946.

"Sharakh" - captured in August of 1941, by RIN. It was incorporated into RIN's fleet under the new name of "Nilam". Returned to Iran in 1946.

"Karkas" - captured in August of 1941, by RIN. It was incorporated into RIN's fleet under the new name of "Moti". Returned to Iran in 1946.

Vessels:

Babr Class (1932, 950 tonnes; 62.4m/9m/3.1m; 15 knots; 4*102mm).

"Palang" - sunk at Abadan (Iran) by the Royal Navy, in August of 1941.

It must also be mentioned that the sloops also suffered significant damage, but were later repaired and returned to service. No detailed information, as of present, is available on their post-intervention condition.
