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.

The Australian government has released two more policy documents that outline its defence development intentions over the next few years. The two documents – National Defence Strategy (NDS) 2024 and Integrated Investment Program (IIP) 2024 – were unveiled by Australia's Minister of Defence Richard Marles on 17 April.

The new policies follow Australia's Defence Strategic Review (DSR) – issued in April 2023 – and its evaluation of surface combatant capabilities, which was released earlier in 2024.

As outlined in the IIP 2024, the Australian government is projected to spend AUD765 billion (USD496 billion) in the decade between 2024 and 2034 on defence programmes. This amount includes an additional AUD56 billion above the previous trajectory that was forecast for this period.

General Atomics Aeronautical Systems, Inc (GA-ASI) has tested a podded gun on its Mojave short take-off and landing (STOL) unmanned aerial vehicle (UAV), the company said in a 23 April release.

GA-ASI mounted two Dillon DAP-6 podded miniguns to the Mojave and tested the combination at the Yuma Proving Ground in Arizona on 13 April. The Mojave performed seven gun-runs during two flights, expending around 10,000 rounds of ammunition against “a variety of targets”, according to GA-ASI. A video accompanying the release showed the UAV destroying a pickup truck.

“For this live-fire demonstration, our goal was to validate the [Mojave's] battlefield relevance,” GA-ASI told Janes on 23 April. “As such, the effort was done completely using GA-ASI's [internal research and development funding], but we believe that successfully demonstrating this capability is of considerable interest to potential customers.”

Integrating the gun pods took “about 70 business days” to complete, added the company.
