The Pu-98 Arraia (Inyursta) or Type-98 Long Lance (Nihon) is a heavyweight torpedo in use by the Inyurstan Navy and Nihonese Navy. It is used on the Type-60 SSP, Type-64 SSN, Mirage-Class SSGN, Type L SSK, Type Junsen SSP, Kairyu SSN, and HA-2008 SSP.

Design

This torpedo is optimized for both stealth and resistance against counter-measures. It utilizes a battery-powered brushless motor to eliminate exhaust and reduce noise from both internal operation and exhaust bubbles. It's multi-band SEQ/US-7 sonar is capable of operating in both passive and active modes, with a 100o horizontal search arc and a 25o vertical search arc in active operation for a wide range of detection. The warhead has a high level of ECCM capabilities against acoustic decoys.

Like most modern torpedoes, the Pu-98 can be fired in a variety of different modes for varying levels of speed and stealth. The two main options are a high speed "sprint" at 70 knots or a low-speed, low-noise cruise across a longer distance. It can be launched in push-out or swim-out mode, and experts believe that when paired with a water ram expulsion system this torpedo is nearly undetectable at most distances and launch speeds.
