Rocket launcher C-90

The C-90 is a rocket launcher that fires a 90mm rocket-propelled grenade manufactured by Instalaza in Zaragoza, Spain.

Features

The weapon is single-use, fired from the shoulder and transportable by a single infant.1 the container-launcher is made of reinforced resin, permanently houses the projectile, and all the elements of the system that are attached to it. The firing mechanism is completely autonomous and lacks electrical components, at the rear of the projectile is the rocket motor with its igniter and stabilizer. The propellant combustion ends before the projectile leaves the launcher. The absence of recoil allows firing in any position and with a stable aim at the moment of the shot.

The VN-38c light intensifier has been designed to provide the C-90 family with operational capability at night or in low light conditions; It is a passive system with low energy consumption that is attached to the C-90’s optical viewfinder by means of a shoe and that does not require any adjustment, since the aim is made with the C-90’s own optics. This system can be used for night surveillance by removing the collimator and inserting where it was, an eyepiece (3.3X) that remains in a hole at the bottom of the VN-38C, in that same hole the collimator that acts as a handle. The previous C-90s that do not have a shoe for the viewer, Instalaza provides a special template to place the shoe. Optionally, the container-launcher can be supplied with a handle (folding) and a shoulder pad, which improve the aiming and firing of the C-90.

Shooting direction

The reusable optronic firing direction, called VOSEL, provides both the C-90 and the Instalaza Alcotán-100 with a high probability of hitting the target.

The VOSEL firing direction has full day / night capability, laser telemetry, target lateral displacement sensor, and future point display.2

It is made up of the following components:

Vision module
Day / night vision mode: the shooting direction is equipped with an optical sight that by activating a 3rd generation image intensifier tube allows the identification of the target at a distance of up to 1,200 m at night.
Telemetry module
A class 1 laser rangefinder, with a range of 2,000 m, determines the distance at which the target is located.
Orientation module
A triaxial sensor provides data to determine the angular shift of the target.
Presentation module
It shows the shooter the information generated by the shooting direction (messages, tracking cross, future point, and combat sight).
Calculation module
It incorporates the electronics that manage all the functions of the fire control:
- Check the status of the firing direction (self-test).
- Identify the type of ammunition and its temperature.
- It receives the information from the telemetry and orientation modules.
- Prepare the information received, following the firing tables incorporated for the different types of ammunition.
- Find the location of the target (future point).
- Transmits future point information to the display module, which displays it through the eyepiece.
  All these functions, including target tracking, take less than 3 s to complete. The elaboration and calculation process takes less than 0.03 s.
Power module
It consists of a 12 V rechargeable battery.
Safety and trip module
It contains the security elements that control the enabling of the direction of fire for the shooter to take the shot.
External elements
Controls, coupling guide with the tube and connection elements.

Versions

There are several versions, specifically designed to beat different targets:

General use: C-90C.
Antibúnker: C-90BK.
Anti-tank: C-90CR.
Armor / Fragmentation (Tandem Warhead): C-90CR-BK.
Smoke / incendiary.
Antipersonnel: C-90AM.
Training: TR-90 (M3)
Each version of the C-90 family has its own warhead, specially designed and manufactured for its specific application.

The C-90-CR (M3) and C-90-CR-RB (M3) are equipped with a hollow charge head with different performances, the C-90CR-RB having the highest armor penetration.

The C-90-CR-AM (M3) also has a hollow charging head, but with a special body that provides a powerful anti-personnel effect.

C-90-CR-FIM (M3) contains more than 1.3kg of a red phosphorous composition, which produces incendiary and smoke-causing effects.

The C-90-CR-BK (M3) carries a tandem anti-bunker warhead. The precursor head pierces the wall and, through the hole, passes the fragmentation head, which explodes inside.

The TR-90 (M3) is a training device externally equal to a C-90, its optical sight being similar; It uses a light alloy arrow (reusable) that is propelled by a shortened 12 cartridge and that simulates the trajectory of the grenade, obtaining a very realistic instruction.

Lastly, the C-90-CR-IN (M3) head is inert, with the same weight, exterior shape and aerodynamic behavior as the real head of an anti-tank system.
