As part of an effort to update its Amazonas-class offshore patrol vessels (OPVs), the Brazilian Navy is acquiring a new air and surface search radar with identification friend-or-foe capability (IFF), according to the Navy Weapon Systems Directorate (Diretoria de Sistemas de Armas da Marinha: DSAM).

The Brazilian Naval Commission in Washington, DC, (Comissão Naval Brasileira em Washington: CNBW) on behalf of the DSAM has requested a request for information (RFI) and the price availability for up to three radars on 25 March.

The navy seeks to recover the combat capability of the OPVs by updating several of the ship's systems, the Navy Directorate-General for Material (Diretoria-Geral do Material da Marinha: DGMM) recently told Janes .

The modernisation of the OPVs will be carried out by the DSAM, the DGMM added, without detailing a schedule and the scale of the effort.

The DSAM is subordinated to the DGMM.

US Naval Air Systems Command (NAVAIR) accepted delivery of the first two Textron T-54 Multi-Engine Training System (METS) aircraft at Naval Air Station (NAS) Corpus Christi, Texas, the service announced on 22 April. The aircraft are set to begin training students at NAS Corpus Christi's Training Air Wing Four in boreal spring 2025, the US Navy (USN) told Janes .

The USN intends to operate 64 of the Textron King Air 200-based aircraft, which will replace the Textron T-44 as the service's main twin-engine pilot training aircraft. Deliveries are set to run through 2026, and the aircraft is meant to operate until 2055.

“This aircraft brings modernised training to student naval aviators and prepares them for the advanced aircraft they will fly in the fleet,” said Captain Duane Whitmer, USN programme manager.

Two Mitsubishi Heavy Industries (Sikorsky) SH-60K helicopters of the Japan Maritime Self-Defense Force (JMSDF) have crashed after they suffered a suspected mid-air collision during a night-time training exercise.

Japan Minister of Defense Minoru Kihara said the incident occurred between 2238 and 2304 h local time on 20 April, while the helicopters were conducting an anti-submarine drill with other JMSDF units. According to Kihara, three helicopters were participating in the drill, 150 n miles east of Torishima Island, in the Izu Islands chain.

“Two of the helicopters were flying in close proximity to each other and we have determined that there is a high possibility that there was a collision,” Kihara said on 21 April.
