L3Harris is to supply a series of next-generation electronic warfare (EW) payloads to equip the MK 234 Nulka active offboard decoy system used by the US and Australian navies.

Nulka is an expendable soft-kill countermeasure designed to seduce radar-guided anti-ship missiles in their terminal homing phase. Under a Naval Sea Systems Command (NAVSEA) contract, potentially worth over USD120 million, the company will supply Advanced Decoy Architecture Program (ADAP) payloads to meet both US Navy (USN) and Royal Australian Navy (RAN) needs.

The original Nulka electronic decoy cartridge combines a hovering rocket payload carrier vehicle (produced by BAE Systems Australia) atop, which is a mounted broadband radio-frequency (RF) repeater payload (produced by Lockheed Martin) that radiates a large ship-like radar cross-section designed to seduce RF homing anti-ship missiles away from their intended targets. In USN service, the Nulka round is fired from the MK 53 decoy launching system.

Babcock finishes selling Frazer-Nash Consultancy to KBR

by Marc Selinger

UK-based Babcock International Group has completed the previously announced sale of its Frazer-Nash Consultancy to fellow engineering company KBR for approximately GBP293 million (USD404.2 million), Babcock said on 21 October.

Babcock first disclosed the transaction in August, saying the divestiture would help reduce its debt. Meanwhile, US-based KBR will expand its international advisory capabilities by obtaining Frazer-Nash, which operates mainly in the UK and Australia.

Frazer-Nash serves government and industry customers in defence and other sectors. Its defence engineering expertise spans areas such as air, land, and naval systems; command, control, communications, computers, intelligence, surveillance, target acquisition, and reconnaissance; space defence; and weapons.

Besides providing the divestiture update, Babcock said its financial performance for the first half of fiscal year 2022 was in line with its expectations, as the company generated revenue of GBP2.2 billion and underlying operating profit of GBP115 million. Babcock plans to release more details about its first-half results on 7 December.

South Korean firm Hanwha Systems has signed agreements with Israeli companies Elbit Systems and Elta Systems, a subsidiary of Israel Aerospace Industries (IAI), to pursue opportunities for technology co-operation and trade.

Hanwha Systems said on 21 October that the agreements – signed at the Seoul International Aerospace & Defense Exhibition (ADEX) – are focused on capabilities such as active electronically scanned array (AESA) radars, urban air mobility (UAM), and avionics.

Hanwha Systems' agreement with Elta Systems will look to collaborate on exporting AESA radars. Such efforts will integrate Hanwha Systems' radar antenna and Elta's radar signal processor, a press release stated.

The co-operation will also look to leverage the companies' joint work on developing an AESA radar for South Korea's KF-21 Boramae future fighter aircraft, which is being developed by Korea Aerospace Industries (KAI).

France's Direction générale de l'armement (DGA) has formally qualified the Thales Sea Fire S-band multifunction active electronically scanned array (AESA) radar ahead of integration into the combat system of the new Amiral Ronarc'h-class Frégate de défense et d'intervention (FDI) frigates.

Announced on 21 October 2021, the qualification milestone follows 18 months of land-based testing performed at the DGA's Site d'expérimentation des systèmes de défense aérienne (SESDA) shore integration facility at Saint-Mandrier, near Toulon, on the Mediterranean coast. The radar is now being transferred to Naval Group to support FDI combat system integration activities.
