Type 93 U-boats carried 16 torpedoes and had various arrangements of deck guns. As with the type 81 and 87, some had only one 8.8 cm (3.5 in) SK L/30 deck gun while others had a single 10.5 cm (4.1 in) SK L/45 gun and some were initially equipped with both. In 1917 some of the boats were refitted with a single 10.5 cm gun and 220 rounds.[citation needed]
These boats carried a crew of 39 and had excellent seagoing abilities with a cruising range of around 9,000 nautical miles (17,000 km; 10,000 mi). Many arrangements from the Type 81, 87 and 93 were also seen on World War II Type IX U-boats when their design work took place 20 years later.[citation needed]
Compared to the previous type 87, the 93s were 5.75 metres (18 ft 10 in) longer, while the pressure hull was 5.98 m (19 ft 7 in) longer.[3] They were 1.2 knots (2.2 km/h; 1.4 mph) faster on the surface, and unchanged at 8.6 knots (15.9 km/h; 9.9 mph) submerged. Range decreased 2,360 nmi (4,370 km; 2,720 mi) at 8 knots (15 km/h; 9.2 mph), to 9,020 nautical miles. They still carried 16 torpedoes with four bow and two stern tubes. Crew size was increased by 3 to 39.
Compared to the following type Large MS, the 93s were 11.95 m (39 ft 2 in)shorter, and 610 tonnes (600 long tons) lighter.[4] Their range was 980 nmi shorter, and speed was .2 knots (0.37 km/h; 0.23 mph) slower on the surface but .5 knots (0.93 km/h; 0.58 mph) faster submerged. The Large MS was intended for the deepest waters and the increased size made it more comfortable and very seaworthy.
Type 93 boats were responsible for sinking 3.201% of all allied shipping sunk during the war, taking a total of 412,419 combined tons. They also damaged 71,202 combined tons.[citation needed]

There were 24 Type 93 submarines commissioned into the Kaiserliche Marine.[citation needed]
By the end of World War I, 375 U-boats of 33 separate classes belonging to 7 general types had been commissioned. More boats were finished after the war and either destroyed or awarded to victorious nations.[citation needed]
