Northrop Grumman announced on 19 October that it has signed a series of memoranda of understanding with South Korean companies LIG Nex1 and Huneed to develop a ‘Joint Surveillance Target Attack Radar System – Korea (JSTARS-K)' solution to meet a Republic of Korea Air Force (RoKAF) requirement for an intelligence, surveillance, target acquisition, and reconnaissance (ISTAR)-capable aerial system.

The company said in a statement that the JSTARS-K solution, which will be based on the Gulfstream G550 business jet, will leverage Northrop's experience in the battle management command-and-control (BMC2) domain to deliver a new “low risk airborne BMC2 capability”.

While the US firm is set to act as prime systems integrator, local companies will ensure interoperability with other platforms and systems in service with the RoKAF, it added.

Production of the G550 ended in 2020, which is why Janes

Elektroniksystem und Logistik (ESG) is to adapt an operationally proven Israeli combat cloud to the needs of the Bundeswehr, the German electronics and mission systems specialist announced on 24 November.

Speaking at the Berlin Security Conference, ESG's director of business development and sales, Simon Volkmann, said that the company is to utilise the Israel Aerospace Industries (IAI) Operational Avionics Layer (OPAL) to develop its Network Enabled Operations Support (NEOS) for the air assets of the German armed forces primarily, but for the other domains also.

Telesat Canada, Loral finish merger

by Marc Selinger

Satellite communications provider Telesat Canada and its majority owner, US-based Loral Space & Communications, have completed their previously announced merger, according to the combined company.

The new entity, Telesat Corporation, said on 19 November that it has begun trading on the Nasdaq Global Select Market, where Loral had been listed, and on the Toronto Stock Exchange.

The transaction, which was first announced in November 2020, is designed to give the satellite operator the benefits of public ownership, including access to capital markets to fuel its growth. Telesat is developing a new constellation of low Earth orbit satellites to provide broadband Internet connectivity worldwide. The Lightspeed constellation will “meet the rigorous requirements of telecom, government, maritime, and aeronautical customers”, the company says.

Under the merger, Telesat Canada and Loral have become subsidiaries of Telesat Corporation, which is based in Ottawa, Canada. Loral continues to own 56% of US-based satellite communications business XTAR, which will transfer to the new company unless its minority owner, HISDESAT, a consortium of Spanish telecommunications companies, exercises an option to buy it. Option expiration terms have not been publicly disclosed.

Roxel demonstrates novel Coanda TVC nozzle

by Richard Scott

Roxel has built and tested prototypes of a novel Coanda TVC nozzle. (Roxel/MBDA)

Rocket motor manufacturer Roxel has developed and demonstrated a novel thrust vector control (TVC) nozzle that seeks to exploit the Coanda effect to achieve deflection.

Prototyped and tested as part of the French/UK Materials and Components for Missiles Innovation Technology Partnership (MCM ITP) programme, the TVC nozzle device has completed cold gas firings to demonstrate performance capability. Hot gas trials are planned to follow.

The Coanda effect – named after the Romanian-born aeronautical engineer Henri Coandă – describes the phenomenon where a jet flow attaches itself to a nearby surface and remains attached even when the surface curves away from the initial jet direction. Disrupting this boundary layer can be used to impart a deflection: in this case, redirecting the exhaust flow from a solid rocket motor can be used to change the thrust vector.
