The Japanese submarine I-28 Its Design and Capabilities

The Japanese submarine I-28 was a significant vessel in the Imperial Japanese Navy during World War II. It was a Type A I-8 class cruiser submarine.

Built in 1942, the I-28 was designed to be a long-range submarine with a large cargo capacity. It had a length of 100 meters and a beam of 9 meters.

The I-28's design allowed it to carry a crew of 86 and had a top speed of 19.2 knots when surfaced.

The Japanese submarine I-28 was a formidable vessel, with a design that showcased its capabilities as a scout and a fighter.

It displaced 2,631 tonnes surfaced and 3,713 tonnes submerged, making it a substantial presence on the water.

The I-28 was 108.7 meters long, with a beam of 9.3 meters and a draft of 5.1 meters, allowing it to navigate through various environments.

Its diving depth was 100 meters, a remarkable feat for its time.

The submarine's surface running was powered by two 6,200-brake-horsepower diesel engines, driving one propeller shaft each.

When submerged, each propeller was driven by a 1,000-horsepower electric motor.

The I-28 could reach 23.6 knots on the surface and 8 knots underwater, making it a fast and agile vessel.

On the surface, it had a range of 14,000 nautical miles at 16 knots, while submerged it had a range of 96 nmi at 3 knots.

The submarine was armed with six internal bow 53.3 cm torpedo tubes and carried a total of 17 torpedoes.
