The US Missile Defense Agency (MDA), in association with Boeing and Raytheon Technologies, on 12 September conducted a test launch of a Ground-Based Midcourse Defense (GMD) Ground-Based Interceptor (GBI), flying a mock-up of the Exoatmospheric Kill Vehicle (EKV), with a three-stage booster operating in a two-stage mode.

The milestone test – in which the third stage was not ignited – demonstrates a new capability for the GBI, allowing it to release the EKV earlier in flight and, accordingly, enable an earlier opportunity to intercept and defeat a missile threat. The MDA designates this new capability as “a 2-/3-Stage selectable GBI”.

The US Navy (USN) and UK Royal Navy (RN) have successfully executed a maritime sensor-to-shooter (S2S) demonstration culminating in the firing of an AeroVironment Switchblade 300 tactical precision-guided missile from an experimental unmanned surface vessel (USV).

Part of a US/UK Interoperability to Interchangeability (I2I) initiative using unmanned/uncrewed systems, the S2S capability demonstration formed part of last month's NATO ‘REP(MUS) 21' exercise off Portugal. The Switchblade 300 weapon was targeted using information from an AeroVironment Puma 3 AE unmanned aerial system (UAS).

Exercise ‘REP(MUS) 21' – an abbreviation of Robotic Experimentation and Prototyping Augmented by Maritime Unmanned Systems – is an annual exercise jointly organised by the Portuguese Navy, the University of Porto, NATO's Centre for Maritime Research and Experimentation, and the NATO Maritime Unmanned Systems Initiative. The event, hosted at the Portuguese Navy's Centre for Operational Experimentation held in Troia, gives NATO allies and partners an opportunity to field and evaluate new uncrewed and autonomous maritime technologies.

Russia to extend service life of UR-100N ‘Stiletto' ICBM to 2023

by Samuel Cranny-Evans

The service life of Russia's UR-100N (SS-19 ‘Stiletto') intercontinental ballistic missile (ICBM) is to be extended to 2023, NPO Mashinostroyenia general director Alexander Leonov told the RIA Novosti news agency on 18 October.

The last UR-100N missile was delivered to Soviet forces in 1985 with a guaranteed service life of 10 years, which Leonov said was repeatedly extended by checking the missile's fuel tanks, the condition of the liquid propellant, and the safety margins of the load-bearing structures.

The first silo-based UR-100N variant entered service in 1979 and was modified three times to become the UR-100NUTTH (SS-19 Mod 3), which carried six multiple independent re-entry vehicle (MIRV) warheads.

The MIRV warheads of 12 remaining UR-100NUTTH missiles are to be replaced by the Avangard hypersonic glide vehicle, the TASS news agency reported in 2018. Many of the remaining silo-based UR-100N series missiles have been replaced by the road-mobile Yars R-24 ICBM.

Meanwhile, the ground-launched P-800 Oniks anti-ship cruise missile that arms the Bastion-P coastal defence system has been modified to enable it to engage land targets, Leonov told RIA Novosti. “It can be used by submarines, surface ships, aircraft, and land-based coastal missile systems,” Leonov said.

Arnold Defense has unveiled a three-round air launcher concept protoytpe for 2.75 inch/70 mm laser-guided rockets. Developed in partnership with Moog Space and Defense Group, the concept demonstrator – designated ‘Trident' – was unveiled at the AUSA 2021 exhibition in Washington, mounted on a Moog Lightweight Dual Rail Launcher.

Weighing approximately 14.5–16.3 kg (unloaded), between 193 and 203.2 cm in length, and 17.8 cm in diameter, the Trident launcher utilises a curved nosecone to increase streamlining and reduce drag. Utilising Moog's Trident Interface Unit, the launcher is designed to be integrated on to a standard missile rail interface across a variety of aerial platforms without necessitating changes to existing fire-control systems software.
