The Squalo-class submarines were a group of four
Design and description
The Squalo-class submarines were essentially repeats of the preceding Bandiera class. They shared that design's problems with stability and seakeeping and required the same bulging of the hull to rectify the problems. They displaced 920 metric tons (910 long tons) surfaced and 1,125 metric tons (1,107 long tons) submerged. The submarines were 69.8 meters (229 ft) long, had a beam of 7.21 meters (23 ft 8 in) and a draft of 5.19 meters (17 ft).[2] They had an operational diving depth of 90 meters (300 ft).[3] Their crew numbered 53 officers and enlisted men.[2]
For surface running, the boats were powered by two 1,500-
The boats were armed with eight internal 53.3 cm (21 in)
