The US Army on 25 April declared Option 2 of the Future Tactical Uncrewed Aircraft System (FTUAS) Rapid Prototyping Program finished, exercising Options 3 and 4 for both Textron Systems and Griffon Aerospace to build and test production-representative Aerosonde Mk 4.8 and Valiant UASs respectively.

“FTUAS program Options 3 and 4 give us the opportunity to demonstrate our Aerosonde Mk 4.8 HQ [Hybrid Quadrotor] UAS and further advance its capabilities before delivering a system for customer test and evaluation,” said Wayne Prender, Textron Systems' senior vice-president for Air Systems, in a statement.

Griffon Aerospace told Janes that the company was “honoured and excited” to be included in the award but declined to respond to further questions.

Five companies competed for the initial FTUAS contract, of which only two – Griffon Aerospace and Textron Systems – made the Option 2 cut-off.

In September 2023 the US Army selected the Griffon Aerospace Valiant and Textron Systems Aerosonde Mk 4.8 HQ for the second phase of FTUAS, which advanced the two designs through critical design review (CDR), the last step before building and testing a prototype aircraft.

The Sirko-S1 modular UGV developed by Ukrainian company SkyLab is designed to support resupply, medevac, reconnaissance, and mining operations. Its dimensions are 1100×800×500 mm with a maximum speed of up to 7.5 m/s. (Mykhailo Fedorov/Ministry of Digital Transformation of Ukraine)

A Ukrainian-made unmanned ground vehicle (UGV), Sirko-S1, is undergoing trials in Estonia during Exercise ‘Spring Storm', held between 6 and 17 May.

The trials will focus on testing the vehicle's minelaying capabilities in collaboration with ASAX Innovation, the Estonian company said on 11 May.

Sirko-S1 is a 4×4 multi-purpose UGV with a 3 hour battery life, 160 mm ground clearance, and 200 kg payload capacity, making it suitable for various tasks. These include transporting cargo, evacuating wounded soldiers, conducting reconnaissance missions, and supporting minelaying and demining operations.

The vehicle, backed by Ukraine's Brave1 defence innovation cluster, has a 3 km operational range that can be extended out to 10 km with a repeater, SkyLab detailed. It is also equipped with a day/night 360° camera.

Along with this, the company is exploring the possibility of adding a “combat turret” to the vehicle, Minister of Digital Transformation of Ukraine Mykhailo Fedorov previously noted.

The UK Ministry of Defence (MoD) has reopened its requirement for a Fleet Helicopter Support Unit (FHSU) provider to deliver a crewed rotary-wing service to the Royal Navy (RN), having seemingly failed to do so on previous occasions.

A notification posted on the UK government's Contract Finder website on 8 May calls for bids for a contractor-owned service to deliver military and non-military personnel for the RN and to enable the conduct of operational sea training and supporting tasks, including the transportation of freight. The MoD requires the successful bidder to be ready to deliver an initial service to specified ships from 1 April 2026, with the contract expected to run for six years.
