The Type 40 Anti-Ship Missile, or Type 40 AshM for short, is the primary weapon of the SDF-Navy against enemy ships, when a direct battle is needed to be fought. It is a heavy, sea-skimming missile, deploying a pair of wings after launch, capable of being launched from the sea, below the sea, from land and in the air, although the latter two are specialized versions of the same missile.

Flight (Mark I-B, Mark II-B and Mark III-B)

The Flight of the Type 40 Anti-Ship Missile knows three stages: Launch, Cruise and Terminal.

Before launch, the Type 40 AShM sits with its wings folded into the body and passively waiting for computer input, for example with target data, in its launcher, be it a torpedo tube, a VLS-cell, a box launcher or on a weapons pylon on an aircraft. Before launch, the missile needs to be programmed with the direction of the enemy, which can be updated via a shared datalink even in mid-flight.

Upon launch, the missile utilizes a procedure known as hot-launch, firing the engines to achieve lift-off and to leave the launcher, entering the cruise phase a few moments later. During this, the missile is guided by the pre-programmed data, eventual updates included, and flies towards the enemy at Mach 0.8 at a height of 20 to 50 metres above the water surface, taking the longest leg of the journey, making course corrections either with the little flaps of the wings or with the thrust vectoring booster. Due to the construction of the Type 40 with radar-absorbant materials, it is harder to detect then most other missiles of this type, further emphasized by the use of rocket fuel generating less smoke then conventional rocket fuel. The Type 40 is ECM-resistant and has a Radar Warning Receiver, warning the Type 40s onboard computer if the missile is detected and locked on by an enemy radar.

Upon entering terminal stage, either as pre-programmed or upon warning from the Radar Warning Receiver, the Type 40 goes into sea-skimming mode, flying around four to five metres above the water surface and beginning the short sprint at Mach 2.8 or 2.9, depending on the version. Guidance is taken over by the onboard active radar, homing in onto the enemy by own radar guidance. Should the enemy attempt to noise-jam the missile, trying to saturate the radar transceiver with false signals and noise, the Type 40 automatically turns on the passive-homing capability, following the radar signals received to their source. The enemy is most probable to intercept and destroy the Type 40 during this stage, due to the enemy vessel's radar being able to, but not bound to, detect and direct fire against the missile, for example from CIWS, which makes the aforementioned stealth-features even more important for a successful operation of this missile. Should the enemy achieve a hardkill against the missile, destroying it in mid-flight, the missile will explode and send shrapnel towards the enemy with the intent to cause at least minor damage, shredding antennae and crew caught in the path.

When the missile hits its intended target, however, the armour piercing warhead does its work, punching through the enemy vessel's armour and exploding inside the vessel, preferably somewhere, where it causes follow-up explosions. This explosion will leave the enemy vessel either crippled, having to limp back to safer waters, or outright sink it.

Versions

The Type 40 can be mounted on ships of every size, including in launch boxes on FACs and VLS-shafts, as well as submarines. Mark IV, the air-launched variation, is a trimmed and slimmed down version for the usage by aircraft. Mark V, a land-launched version, is in development.

Mark II-B can be equipped with a nuclear warhead with a weight of 450 kg.

Mark T are Training Missiles for handling and operating the Type 40 and are therefore filled less fuel, replacing that with bright yellow paint, 'exploding' once handling mistakes were detected by the electronics or when fullfilling the mission, in essence slamming into the practice target.

History

In the early 2000s, the SDF-Navy began to look for a replacement for the Cláirseoir-AShM, a short-ranged AShM, which was simply wasn't suitable for service anymore as exercises with friendly nations demonstrated time and time again.

Several designs were compared and the Type 40, a design by the Creachadóir Design Bureau was chosen - CDB lacked the production capabilities and SDY was awarded with the contract for the serial production of the Type 40 (we later bought CDB, it became our research facilities in Tipa).

Except on exercises, no Type 40 were fired in combat - until the fateful day in 2012, when a strike-force of the SDF-Navy attempted to enter Marley Bay in Halfblakistan, meeting opposition by naval and air forces. The accompanying FACs returned fire at the enemy ships, using Type 40 Mark III missiles, overwhelming the enemy defenses and hitting multiple ships, sinking one and heavily damaging a destroyer, thus enabling the Selkie-fleet to break off the engagement and retreat.

In 2017, the Allanean Navy bought the DPRs for the Mark II and 1,000 missiles of that model for roughly 385 billion NSD.
