Information and network technology specialists at the US Department of Defense (DoD) are poised to evaluate potential solutions to meet multi-input, multi-output (MIMO) requirements for on-the-move tactical communication networks.

Industry submissions for the distributed MIMO (D-MIMO) development effort are due to the department's Research and Engineering directorate by the end of June, according to the request for sources (RFS) solicitation issued in April. The D-MIMO programme is part of a larger DoD-led advanced mobile communications development effort known as the Innovate Beyond 5G (IB5G) programme.

Research and development (R&D) work conducted under the IB5G umbrella will focus on design, prototyping, and integration of “novel IB5G network concepts and components” to support the department's data-centric networked communication strategy.

Specifically, the IB5G initiative is looking to leverage advanced technology concepts like human-to-machine and machine-to-machine interfaced communications and scaling those systems and applications to the internet of things (IoT), according to the RFS.

The Brazilian Army is to acquire 12 Sikorsky UH-60M Black Hawk utility helicopters to replace its eight HM-3 Cougar and four HM-2 Black Hawk helicopters, said Army Commander General Tomás Miguel Miné Ribeiro Paiva during a 17 April presentation to the Brazilian Committee on Foreign Relations and National Defense.

Gen Tomás noted that the fleet is to be purchased through the US Foreign Military Sales (FMS) programme and entails purchasing surplus helicopters, which will be refurbished before transfer to the Brazilian Army Aviation Command (CAvEx).

The acquisition is being carried out as part of the Army Strategic Program Army Aviation (Prg EE Av Ex). The phasing out of the Cougar and Black Hawk helicopters was approved in December 2023.

The HM-3 is fielded by the 2nd Army Aviation Battalion and the 3rd Army Aviation Battalion, and the HM-2 is deployed by the 4th Army Aviation Battalion.

Initial flight trials demonstrate Excalibur FTA ‘fit for purpose‘, says Leonardo

Initial flight trials of the 757 airframe that is to be converted to the Excalibur Flight Test Aircraft (FTA) project to de-risk the Tempest future fighter have shown it to be “fit for purpose”, an official from Leonardo told Janes .

Speaking at a UK industry showcase event for the future combat air power, including the Global Combat Air Programme (GCAP) of which the Tempest demonstrator is a part, Dave Morris, head of campaigns Future Combat Air – GCAP at Leonardo, said the first round of flight trials out of Ministry of Defence (MoD) Boscombe Down in southern England had gone well and that there should be no issues ahead of fitting aircraft with its Tempest mission equipment.

New aerial vehicle seen on Chinese H-6 bomber

by Akhil Kadidal

This conceptualised graphic of a new air-launched vehicle recently carried by a Xi'an H-6MW bomber is based on a low-quality photograph. The new air vehicle is possibly based on the design and development of other Chinese air vehicles such as the WZ-8 and MD-22, and a new HSV. (Janes)

A Chinese Xi'an Aircraft Company (XAC) H-6MW bomber has been photographed in flight while carrying a new type of air-launched vehicle.

The H-6MW is a specialised, cruise missile-carrying variant of the People's Liberation Army Air Force's (PLAAF's) strategic bomber. Janes has previously assessed that the aircraft is the airborne launch platform for the Aviation Industry Corporation of China (AVIC) WZ-8 supersonic, high-altitude reconnaissance unmanned aerial vehicle (UAV).

However, the new aerial vehicle seen carried by the bomber differs in design from the WZ-8, suggesting it could be part of a new programme to develop a supersonic or hypersonic air vehicle. A photograph of the H-6MW carrying the new aerial vehicle first appeared on Chinese social media from the third week of April. The programme is likely inspired by the WZ-8 programme.
