Flat submarine. Compared with 6 13 submarine, Type 33 submarine mainly has the following improvements: two torpedo tubes are added to improve the performance of underwater acoustic equipment, the battery water cooling system is added, and the diving depth is increased. The state of the snorkel is as follows.
The main sailing conditions increased the speed. By turning the reserve buoyancy into overload fuel, the endurance and self-sustaining power are skillfully doubled. As a result, the power plant has not changed, and it is discharged by improving the hydrodynamic and propulsion characteristics.
After the water volume increases, the underwater speed of the ship remains unchanged. It should be said that the design of Model 33 is quite successful.
Weapons and equipment: 8 torpedo tubes, 2 radars and 4 sonar. He served for 25 years and sailed safely at 24,000 nautical miles. Main operational tasks: destroy enemy transport ships and large and medium-sized ships, destroy onshore bases and important targets, and undertake anti-submarine and mine-laying transportation tasks.
