Hanoi has issued a diplomatic note to Putrajaya after a Malaysia Maritime Enforcement Agency (MMEA) vessel collided into a Vietnamese fishing boat in disputed waters of the South China Sea, multiple sources close to the matter confirmed to Janes .

Vessels involved in the collision are the MMEA's sole Arau (Nojima)-class offshore patrol vessel (OPV) KM Arau and an unnamed fishing boat with pennant number 90729.

The collision took place on 22 April at about 15 n miles southeast of Investigator Shoal, which lies within the Spratly Islands cluster. The feature is occupied by Malaysia, but also claimed by China, Vietnam, and Taiwan as part of their respective maritime territories.

As a result of the collision, 22 fishermen from 90729 fell overboard and a search-and-rescue operation (SAR) was established by both the Vietnamese and Malaysian authorities.

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.
