UK Royal Navy trials radar new bathymetry software

by Richard Scott

Novel radar bathymetry software that enables surface radar returns to profile the seabed has been trialled on board the UK Royal Navy (RN) survey craft HMS Magpie, according to the RN.

Jointly developed by the National Oceanography Centre (NOC) in Liverpool and the Defence Science and Technology Laboratory, the software analyses sea clutter images produced by waves on a standard X-band marine navigation radar to generate a bathymetric profile and surface current assessment. This means that a detailed bathymetric profile can be output in a matter of hours without the need for the vessel to physically sail over the area being surveyed.

Magpie undertook trials of the new radar software during trials off Plymouth Sound earlier this year using a standard X-band radar system temporarily installed on a roof rack assembly. According to the RN, it took just a few hours to map the sea floor on the approaches to Plymouth using radar, whereas it might have taken two weeks to capture sonar bathymetry.

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.
