10 Apr 12. Raytheon UK has been awarded a Paveway IV replenishment contract by the MoD as part of a deal worth £60 million. The contract, signed last December, was announced against the backdrop of a media briefing day held at the company’s Defence Head Office in Harlow on 3rd April.

The 500lb GPS precision-guided Paveway IV was first deployed in Afghanistan (OP HERRICK) in November 2008 and continues to equip Tornado GR4 aircraft in that theatre. The weapon was also used on Tornado in support of the air campaign over Libya (OP ELLAMY) in 2011 and is due to be fitted to Typhoon aircraft from 2013. “In about three and half years of operational deployment we’ve released over 1,000 combat weapons” said Terence Marsden, the programme’s Chief Engineer. “We’re nearing close to 100% reliability” he added.

Paveway IV is designed to be interchangeable between different platforms. While the Tornado can be fitted with up to five Paveway IV, the Typhoon will be able to carry six. The weapon will also be integrated onto the RAF’s Joint Strike Fighter aircraft, which will be able to carry Paveway IV both internally and externally.

Marsden went on to outline spiral developments of Paveway IV within the UK MoD’s future strategy for precision-guided weapons (known as the Selective Precision Effects At Range (SPEAR) capability). The company would like to make a “family of warheads” explained Marsden, which would cover: a low collateral warhead, a compact penetration warhead and an enhanced moving target capability. The company is currently investing in fragmentation modelling and is working closely with QinetiQ on penetration warhead developments.

The Paveway IV replenishment contract will sustain 450 jobs within Raytheon UK’s Defence operations. Defence activities account for around two-third’s of the company’s UK business across three main sites: Harlow (C4ISTAR, Force Protection, Precision Effects and Air Traffic Management Systems), Waddington (Sentinel/ Airborne Stand-Off Radar (ASTOR) aircraft support) and Broughton (special mission aircraft). In addition the company has staff located at customer sites in the UK and abroad (including Catterick, Sennelager and Warminster) providing training and support services.

David Pile, Raytheon UK’s Defence Business Development Director, presented Landshield – the latest addition to the company’s range of GPS anti-jamming devices produced by the Force Protection site at Harlow. GPS requirements are ubiquitous, providing location information and precise timing signals for synchronising systems and networks. However, the GPS signal is extremely weak and easily susceptible to jamming. The company’s expertise in GPS anti-jam devices stretches back over 20 years and it has been particularly successful with the analogue GAS-1 product.

The private venture Landshield is a small, next generation, lower-cost digital device providing a stand-alone ‘plug-and-play’ solution for land vehicles. The equipment can also be networked across several platforms, providing a triangulation capability. Potential applications include: navigation systems, sensors, communications and weapon systems. “At the moment there are very few competitors out there doing this” said Pile. “We believe we’ve, hopefully, captured a niche”. Pile also confirmed that “the product is now pretty much fully developed” and that Landshield is scheduled to be available for purchase from late 2012.

On the air systems side, Raytheon UK is currently investing in the Broughton facilities where the company integrates systems for the Shadow intelligence, surveillance and reconnaissance (ISR) aircraft. Based on the Hawker Beechcraft King Air 350CER, the Shadow accommodates two pilots and five mission personnel. There are currently four aircraft in service with the RAF and a fifth aircraft was delivered on 12 Dec 11. Paul Francis,
