MDA, SDA satellite efforts look to mature RF, optical broadband capabilities

The recent launch of small satellite platforms by the Pentagon's Missile Defense Agency (MDA) and Space Development Agency (SDA) represent milestone moments in the department's effort to advance networked, space-based radio frequency (RF) and optical broadband communication capabilities.
The MDA CubeSats were launched into orbit in late June aboard a LauncherOne rocket developed by Virgin Orbit subsidiary VOX Space, LLC, according to an MDA statement on the operation. The launch was conducted as part of the CubeSat Networked Communications Experiment (CNCE) Block 1 programme, under the agency's Nanosat Testbed Initiative (NTI). The pair of CubeSats are expected to remain on orbit for 90 days, which could be extended to a full year pending the results of the ongoing experimentation.
The NTI is designed to leverage “small, low-cost satellites to demonstrate networked radio communications between nanosatellites while in orbit”, agency officials said in the statement. “Transmitting data between interceptors, sensors, and communication systems is critical to a missile defence architecture that must quickly identify, track, and destroy incoming enemy missiles before they reach their targets,” they added.

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.

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.

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.
