P-190 "Spearhead" anti-ship and land-attack missile


Developed as a successor to the SS-N-19 and SS-N-19B anti-ship missiles. The P190 is a new anti-ship missile designed to provide optimum speed and destructive power for even relatively small ships. Spearhead missiles can be used by a cruiser to kill a carrier, for example, and will fit the launch cells for the existing SS-N-19 missile with only a little modification to the cells.

Warhead types

1) 800Kg HE
2) 710Kg APHE-DU
3) 320Kt nuclear
4) Chemical
5) Biological
6) FAE (equivalent to 80Kt HE detonation)
7) Guided* cluster munitions** (armour piercing, HE, anti-personnel etc)
8) Smoke.

The warhead types available allow a high degree of flexibility when the P-190 missile is employed. As well as relatively conventional warheads such as nuclear and explosive, the P-190's ability to deliver cluster munitions makes it devastating when employed against carriers, in which role it can scatter hundreds of bomblets over the flight deck of the ship. When employed to generate smoke, the P-190 can generate (by dispersing and igniting an oil/gelatine mixture) a smoke cloud of a size 40x40x30m (approximately), which can persist for up to 45 minutes in optimal conditions, interfering with enemy LADAR and laser ranging systems and doing damage to any surface to which it sticks.


Guidance systems

The P-190 missile employs a similar guidance system to that seen on the SS-N-19B/P-700M missile. In this system, the guidance arrays are arranged as below:

This gives optimal coverage of all possible emissions and returns from the target, without interfering with with main radar array. The guidance computer uses all of the available guidance systems to maintain an accurate lock with its target. The P-190's radar systems are improved versions of those on the P-700M missile.

The P-190's computer can also be assigned to a specific target or target type, or a specific area of the target. For example, should the user specify, the missile could be ordered only to attack targets matching the profile (in terms of size, electronic emissions, LADAR emissions and thermal emissions) of a Nimitz-class aircraft carrier. The missile could then further be programmed to attack a specific section of the hull or superstructure. This capability makes the P-190 a far more flexible weapon than the P-700 Shipwreck or its upgraded cousin.


Propulsion

The P-190 is propelled by a similar arrangement to the 3M82 "Sunburn" missile. In this arrangement, the central part of the missile is a solid-fuel booster rocket. This propels the missile to the speed (Mach 1.0) required for the four ramjets surrounding the missile body to activate. These ramjets then accelerate the missile to Mach 2.2. The missile's final propulsion system, however, is a quartet of small, lightweight turbojets mounted between each ramjet. These are used to give the missile added range and velocity, allowing the weapon to achieve its high range and terminal-stage speed.


Flight control

Guided by INS to the target's general area, the P-190 missile is controlled in flight by four guidance fins, arranged in a cruciform manner just to the rear or the ram air intakes. These guidance fins act as elevons for the missile. These are augmented by four smaller elevons at the tail. All engines are provided with 3D thrust vectoring to allow higher agility should it be necessary. The P-190's flight-control computer can also be set to follow a certain altitude flight profile, e.g. Hi-Mid-Lo (350m-200m-15m), allowing the optimum possible range to be gained without compromising the weapon's defence-penetration and destructive abilities.


Protection

The missile's nose and body are covered with heat-resistant armoued tiles, similar to those on the Yakhont AShM, to provide a measure of protection against CIWS systems and near-miss missile detonations.

*When used for deployment of these, the missile's approach altitude during terminal stage is approximately 150m. The cluster minutions are released when the flight computer indicates that at least 40% of the munitions will impact the target area. The munitions are guided onto their target by individual MMW radars.

** These munitions can also take the form of submunitions, as in the AHEAD round. In this case, the missile approaches from normal altitude and speed and attacks only the suprestructure, aiming to destroy radars etc and cause casualties.

The P-190 will be on sale, though we do check on all customers before selling and reserve the right to refuse sales. If you are interested in purchasing this weapon, please post in Red Star Industries (see my signature) saying how many missiles and what warhead types you're after.

OOC: Interested in this thing, but I'm still trying to consider if it's worth upgrading the weapons on my one thousand Aquadragon-class Ekranoplans which are currently armed with modified Yakhonts.
