LCTE EW: reusing rapier components for training purposes
Short
The Rapier air defense system, introduced into the Swiss Army in the 1980s, has gradually lost its military significance. With the 2020 Armed Forces message, Parliament decided to decommission the system. Instead of completely phasing it out, it was decided to reuse parts of the system for training purposes.
As part of the DDPS innovation spaces, armasuisse Science and Technology (S+T), under the direction of Jens Rehanek, developed the innovation expedition Low Cost Trainings Emitter Electronic Warfare (LCTE EW). At its core is the Rapier system’s search radar, which will simulate ground-based threats during training flights and thereby enhance the training of fighter jet and helicopter crews. The LCTE EW promises significant cost savings compared to commercial alternatives and is expected to be operational by the second quarter of 2025.
Integration of Rapier Components
Under the guidance of armasuisse S+T, selected search radar components from the decommissioned Rapier system were recovered and reconditioned. The available infrastructure and the expertise of armasuisse S+T staff allow for an efficient process tailored to the needs of the air force.
This expedition offers an innovative way to implement a simulated ground-based air defense system, allowing helicopter and jet crews to train in the use of their self-protection systems. Pilots learn to evade ground threats through tactical maneuvers or terrain cover. Repurposing Rapier components enables training in familiar surroundings and specific terrain. The reuse of these flexible system components provides significant technical advantages and optimizes the use of personnel resources.
Conclusion and outlook
The LCTE EW expedition contributes to knowledge development for effectively supporting potential procurement projects. A particular challenge was extracting specific Rapier parts during an ongoing decommissioning process. Necessary assessments showed that a legally compliant reuse is possible despite the ongoing decommissioning.
Initially, armasuisse S+T will support the training of air force specialists to enable them to operate the system independently. Additionally, armasuisse S+T will offer consulting support and assume repair and maintenance responsibilities. This allows for significant savings in terms of personnel and training infrastructure. The ability to train in their own environment further increases training efficiency and sustainably boosts the operational readiness of the air force.
