FOAS (FUTURE OFFENSIVE AIR SYSTEM), UNITED KINGDOM



The Future Offensive Air System (FOAS) is the name given to a number of concept options being examined for the UK Ministry of Defence's requirement to replace the capabilities provided by the Tornado GR4 aircraft. The aircraft and airborne systems developed under the FOAS initiative will become operational around the year 2018, when the Tornado GR4s have reached the end of their operational lives. The FOAS research program is running in parallel to two major UK defence initiatives - on the new future aircraft carrier (CVF) and on the Future Joint Combat Aircraft (FJCA), formerly known as the Future Carrier Borne Aircraft (FCBA), for which the STOVL (short take-off vertical landing) variant of the F-35 Joint Strike Fighter was chosen in September 2002. An "initial gate" decision, which will move the project into the assessment phase, is expected in 2004. Procurement decisions are expected in 2008.


BAE SYSTEMS is examining the best combined force mix, comprising manned aircraft, uninhabited air vehicles (UAVS) and conventional air-launched cruise missiles (CALCMs).


MANNED AIRCRAFT


Options being evaluated for the FOAS Manned Aircraft include variants of developed aircraft such as the Eurofighter and the Joint Strike Fighter (JSF), rather than dedicated new build design aircraft. The manned aircraft will operate in long-range, low-level missions, using stealth technologies and terrain screening. Electronic warfare research areas being examined include multisensor data fused networks, more powerful radar and countermeasures processors, and the frequency dependence of stealth technologies, sensors and decoys. The new build aircraft concept may carry the range of current and future weapons in the UK inventory, including internally mounted large air-to-surface weapons, together with an extensive external payload.


MBDA has been selected to evaluate the possibility of using the Airbus Military A400M as a platform for air-launched cruise missiles as part of the FOAS programme.


UNINHABITED AIR VEHICLES


Uninhabited air vehicles (UAVs), which are currently used for surveillance, weapon targeting, command and control, as well as for electronic warfare, are being studied within the FOAS programme. A range of UAVs will be deployed. Intelligence, surveillance, reconnaissance and combat UAVs are capable of operating autonomously or in cooperation with manned aircraft to increase operational flexibility and reduce aircrew loss or capture during high-risk missions.


CONVENTIONAL AIR-LAUNCHED CRUISE MISSILES


Conventional air-launched cruise missiles are an integral part of the FOAS force mix, through the launch of waves of stand-off weapons from positions behind the front line. Studies of fire-and-forget missile technologies are underway on propulsion, on guidance (using millimetre-wave and imaging infrared with focal plane arrays) and on robustness against countermeasures. The CALCM studies are assessing the viability of a range of concepts for the deployment of large numbers of cruise missiles launched from adapted airliners, military transporters or maritime patrol aircraft. Both internal and external carriage options are under evaluation, with launch, command, control and operational issues also playing a key part in force mix assumptions.


Two parallel studies have been contracted by the MOD, to MBDA (formerly Matra BAe Dynamics) and Aerosystems UK. MBDA, teamed with Lockheed Martin Aeronautical System, BAe Airbus and Flight Refuelling Limited, has been contracted to perform feasibility and concept studies for both the overall FOAS CALCM system and the missile itself.


Studies are considering all aspects of weapon carriage and release, ground handling, stores management, and operational analysis. MBDA is making use of advanced technologies such as synthetic environment to ensure that the current feasibility studies deliver the most technologically advanced and cost-effective solution.


MBDA studies to date have defined a FOAS-CALCM solution, which consists of a combination of advanced cruise missiles, modular carriage and release concepts, datalinking to satellites, JSTARS or other command, control, communications, computers and intelligence (C4I) assets, and real-time battle damage assessment. The output from the studies will support the forthcoming MoD combined operational effectiveness and investment appraisal (COEIA).


MBDA also maintains a key position as weapon supplier in the team developing the technology demonstrator programme, with inputs into demonstrators aligned with the new breed of cruise missile system envisaged for the future FOAS mission.


Aerosystems International, based in Yeovil and teamed with Aerostructures Hamble Limited, Frazer Nash Consultancy Limited and Flight Refuelling Limited, has been contracted to carry out concept studies of CALCM systems to generate performance parameters that will be used in the MOD's formulation of technology demonstration and system prototype programmes.


C4ISTAR


Teams led by BAE Systems and LogicCMG have been given contracts by the UK Ministry of Defence to investigate technologies for Command, Control, Communications, Computers, Information/Intelligence, Surveillance, Targeting Acquisition and Reconnaissance (C4ISTAR) in support of the FOAS programme. The BAE team includes: EDS Defence, AMS, Lockheed Martin, Aerosystems International, Northrop Grumman IT Europe, Royal Military College of Science, MBDA and Astrium. LogicaCMG is teamed with Raytheon, Qinetiq and EADS Germany.

MOD FOAS description
Description
The Strategic Defence Review recognised a continuing need for a long-range offensive air capability beyond the withdrawal from service of Tornado GR4.

FOAS is planned to fill the resulting Deep Strike capability gap.


In essence, the unique FOAS requirement hinges on provision of a capability to strike with precision and in a timely and controlled manner at fixed, relocatable and mobile hardened and soft targets in the deep by day and by night and in all weather conditions.


The FOAS programme currently consists of ‘System of Systems’ concept studies and technology demonstration projects.


Candidate system components could include manned aircraft; uninhabited air vehicles; cruise missiles; and a command, control, communications, computers, and intelligence (C4I) system.




General characteristics / technical performance
Integrated, flexible, all-weather, day/night, survivable, easily supportable, and interoperable with allies.



In-Service Date (ISD)
Nominally, 2017 (individual system components could have different ISDs).



Major Milestones
Initial Gate (when the programme will move from the Concept phase into the Assessment phase) is planned to be in the latter part of 2004.



Quantities 
It is far too early in the programme to determine the numbers of any individual system component.


Commercial Aspects
There are currently contracts placed on industry for concept and technology work.
