''The Nudelman-Suranov NS-45 (also known as NS-45 for short)'' is an extended and much larger version of the [[NS-37 (37 mm)|NS-37]] aircraft autocannon. It was made for the [[Yak-9K]] (The "K" stands for "Krupnokalibernyi", which means "larger calibre") specifically, but it was proven to be unsatisfactory as the autocannon stressed the aircraft's airframe way too much to be viable and reliable. Only 44 Yak-9Ks were equipped with the NS-45, but a prototype night fighter version of the [[Tu-2]] called the Tupolev Tu-1 carried two of these cannons under its nose, together with a pair of NS-23s on its wings. However, the Tu-1's Am-43V engines were not ready for production so only a prototype version of the aircraft was created.

The NS-45 is a 45 mm autocannon chambered in the 45 x 186 mm shell. It is fed trough a belt of 29 rounds (sometimes 15 rounds) and its recoil operation is short action based. Its length was approximately 252 cm and its mass is 152 kg.

Description

The Nudelman-Suranov NS-45 (also known as NS-45 for short) is an extended and much larger version of the NS-37 aircraft autocannon. It was made for the Yak-9K (The "K" stands for "Krupnokalibernyi", which means "larger calibre") specifically, but it was proven to be unsatisfactory as the autocannon stressed the aircraft's airframe way too much to be viable and reliable. Only 44 Yak-9Ks were equipped with the NS-45, but a prototype night fighter version of the Tu-2 called the Tupolev Tu-1 carried two of these cannons under its nose, together with a pair of NS-23s on its wings. However, the Tu-1's Am-43V engines were not ready for production so only a prototype version of the aircraft was created.

General info

The NS-45 is a 45 mm autocannon chambered in the 45 x 186 mm shell. It is fed trough a belt of 29 rounds (sometimes 15 rounds) and its recoil operation is short action based. Its length was approximately 252 cm and its mass is 152 kg. It had a muzzle velocity of 780 m/s which is quite decent for an aircraft mounted autocannon, and the rate of fire of 260 to 280 shots a minute.

It had huge amounts of recoil, so much so that if the pilot was flying at lower speed, they could be violently shook back and forth. This high amounts of recoil also meant that the airframe would be under heavy stress. Numerous oil leaks and water leaks could be sprung after the autocannon was shot.

While it was very effective at taking down aircraft targets, it could not be aimed realistically past the first shot. This lead to the abandonment of mass producing the aircraft and the cannon.

Usage in battles

Due to the NS-45 high inaccuracy after the second shot, it is recommended to use it like a sniper rifle; precisely aimed shots will demolish any smaller aircraft if hit centre mass. While it may be quite a task to use it against enemy fighters, if the user is accurate enough, the hits will mostly result in a complete destruction of the enemy fighters and because the cannon has limited ammo, the user will have to learn how to properly aim the cannon.

If the player does not trust the cannon to take down fighters, the other way of using it is for bomber hunting. Due to the NS-45 astonishing power, a single hit will incapacitate a bomber most of the time, either by ripping off their wing, tail or by lighting them on fire or rarely, a complete destruction of the bomber, it is highly useful for sniping bombers at higher altitudes. Because of the bombers being a very large target, and the NS-45 pretty decent velocity, it makes it rather easy to reliably kill bombers at the distances of up to 1.50 km.

Pros and cons

Pros:

  • Decent velocity (takes some time to get used to)
  • Almost always one shots or leaves critical hits
  • Quite accurate after the "New Cannon" upgrade is unlocked
  • Tracer and the bullet itself is bright and large, allowing for easier aim re-adjustment

Cons:

  • Hard to lead
  • No spray capability
  • No AP shells for mixed battles like that on the similar NS-37 on the Yak-9T
  • Inferior in fire rate and accuracy compared to NS-37

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

Media

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
