Hensoldt is set to upgrade 82 Bundeswehr type NH90 tactical transport helicopters (TTH) with self-protection technology.

The sensor solution provider will deliver its airborne missile protection system (AMPS) for the helicopters.

According to Hensoldt, the AMPS will also include the Hensoldt radar warning receiver, Kalaetron, as a component for the first time.

Following the integration phase, the helicopters will be upgraded as per the framework of the THOR project (TTH Operational Revision Programme), from 2025.

This comes after a sample deployment of the Hensoldt AMPS-MLR electronic warfare system, in the German NH90 TTH, was sanctioned during the 94th session of the Defence Committee of the previous parliamentary term.

In a statement, Hensoldt said: “The proof flights with the Kalaetron on the CH53 helicopter, at the Wehrtechnische Dienststelle 81, in June 2020, spoke in favour of the sensor solution provider Hensoldt.

“In the end, the decision-makers WTD81, BAAINBw, as well as Airbus Helicopters, came to the conclusion that the Hensoldt solution, consisting of the missile launch detection sensor MILDS Block2, the passive laser warner ALTAS-2QB, the Kalaetron, the AMPS control and display unit ACDU, as well as a counter measure dispenser system, represented the most future-proof concept, compared to the competitors.”

As a protection system, AMPS detects missile, laser, and radar threats, and automatically commences targeted countermeasures.

The modular design of the system is expandable with laser sensors, radar warning sensors, or laser countermeasures.

The Kalaetron radar warning receiver also quickly detects and recognises threats.

Due to its completely digital design, in a wide frequency range, it has a low false alarm rate.

Earlier this month, Leonardo concluded the acquisition of a 25.1% stake in Hensoldt.
