The MANTIS system is intended to detect, track and shoot down incoming projectiles before they can reach their target within very close range. The system itself is based on Oerlikon Contraves' Skyshield air defence gun system. A MANTIS system consists of six 35 mm automatic guns (capable of firing 1,000 rounds per minute), a ground control unit and two sensor units. The guns fire programmable AHEAD ammunition, developed by Rheinmetall Weapons and Munitions - Switzerland (formerly Oerlikon Contraves Pyrotec). The ammunition carries a payload of 152 tungsten projectiles weighing 3.3 g (51 gr) each.
The MANTIS radar can acquire a target within two seconds, then engage it with one of the guns firing a 36-round burst. Two guns directed by one radar each can engage multiple targets. After being manually activated, the system operates fully automatically.[2]
Originally, the German Army ordered a first batch of two systems in 2009, to be delivered in 2013, with two more systems planned to follow later but these were never bought. Both MANTIS systems were transferred to the German Air Force, which is responsible for all air defence tasks. The German Air Force took possession of the first MANTIS system on January 1, 2011.[3] It was first deployed to Mali at the end of 2017, although without the guns.[2]
The first two systems cost around €110.8 million, plus another €20 million for training and documentation purposes. In a follow-on contract, worth around €13.4 million, Rheinmetall would also deliver the corresponding ammunition to the Bundeswehr.[4]
On 7 February 2023, Germany announced it would be donating the two MANTIS systems to Slovakia to strengthen Slovak air defences permanently.[2][5]
On 24 October 2023, The Armed Forces of the Slovak Republic (Ozbrojené sily Slovenskej republiky) took over the Mantis air defence system from the German Air Force at the 11th Air Force Brigade in Nitra. Their task will be to strengthen the protection of the eastern border with Ukraine.[6][7]
