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.

Embraer Defense and Security is to carry out the mid-life upgrade (MLU) of 68 of the EMB 314 (locally designated A-29) Super Tucano training and light attack aircraft of the Brazilian Air Force, the service's commander Lieutenant Brigadier Marcelo Kanitz Damasceno said on 17 April during a presentation to the Brazilian Committee on Foreign Relations and National Defense.

The MLU is intended to extend the lifespan of the aircraft by up to 25 years, Lt Brig Damasceno said, and follows a June 2023 agreement between Embraer and the Brazilian Air Force to study a technological refresh of the Super Tucanos, although details were not disclosed.

Brazil purchased 25 A-29A and 51 A-29B aircraft in 2001, adding eight A-29As and 15 A-29Bs in 2005. The fleet was received between 2003 and 2012.
