Diehl Defence is evolving a fire-on-the-move capability for the IRIS-T-SLS (Surface Launched Short Range) mobile air defence interceptor system.

IRIS-T-SLS uses an unaltered IRIS-T (Infra Red Imaging System - Tail/Thrust vector-controlled) air-to-air missile. The interceptor is fired vertically from a launcher mounted on an all-terrain vehicle - for a 360 short-range air defence (SHORAD) application - where the missile's infrared seeker will be able to lock-on-before as well as lock-on-after launch following target designation by the ground station's battle management system.

In the air-defence role, the IRIS-T-SLS system is currently designed to be fired from a static deployed all-terrain vehicle. Diehl cites the Unimog 5000 4x4 multipurpose all-wheel drive medium truck in its marketing literature as its default IRIS-T-SLS launch platform, although the system is essentially platform 'agnostic', and can be adapted to country-specific transport and launcher vehicles with a variable frame system.

Speaking at the IQPC Integrated Air and Missile Defence 2017 conference in London in late March, Michael Masur, GBADS Head of Marketing, Diehl Defence, told Jane's that the new fire-on-the-move concept had already been finalised and that the company is now in the "realisation phase for this development."

Masur said that the fire-on-the move concept envisages a single platform - manned by a crew of three: driver, gunner, and commander - with an integrated sensor, and a four-missile load out mounted on a bespoke launcher which has been "specifically designed and engineered to enable release of the missile while the platform is one the move".

Different platforms are being considered, said Masur, but the default platform for demonstrations is likely to be the Hagglunds BV206, although the concept will focus on demonstrating firing from the launcher on the move and so the platform is not necessarily significant at this stage. "It is important for us to demonstrate that the missile(s) can be launched when the platform is moving at its full driving speed - we do not want to limit the manoeuvrability or speed of the vehicle," he added, noting that the idea is to be able to fire a missile at whatever ground speed the launch platform is capable of achieving.
