The defence secretary has unveiled plans for a new RAF fighter jet, the Tempest, which will eventually replace the Eurofighter Typhoon.
Speaking at the Farnborough airshow, Gavin Williamson unveiled a concept version of the sixth-generation fighter jet the Ministry of Defence (MoD) expects to emerge from its new combat air strategy, designed to maintain the UK’s status as a so-called “tier one” military power after Brexit.
“This is a strategy to keep control of the air, both at home and abroad, to remain a global leader in the sector,” Williamson said.
“We have been world leader in the combat air sector for a century, with an enviable array of skills and technology, and this strategy makes clear that we are determined to make sure it stays that way.”
He said he wanted the Tempest to be flying alongside the existing fleet of Typhoons and the US-made F-35s by 2035.
The Tempest will be able to fly unmanned, according to plans released by the MoD, and will have next-generation technology on board designed to cope with modern threats.
This will include “swarming” technology that uses artificial intelligence and machine learning to hit its targets, as well as directed energy weapons (DEW), which used concentrated bursts of laser, microwave or particle beam energy to inflict damage.
“Fully unmanned operation has not matured yet,” said Air Commodore L. S. Taylor, Assistant Chief of Staff, Capability Delivery Combat Air, and ISTAR at the RAF.
“It is more likely that next generation platforms will be optionally piloted rather than unmanned”.
With France and Britain going their ways, both turn to manned aircraft for their future programs. France is pursuing a similar program with Airbus.
London’s decision to develop its own fighter doesn’t mean going alone all the way.
MOD is to set up a dedicated team to deliver the combat air acquisition program and deliver a business case by the end of the year, to initiate discussions with potential international partners by next summer.
Saab could be a candidate for such cooperation.
Part of the justification for the huge investment is retaining the combat air sector currently responsible for a turnover in excess of £6bn a year that has made up over 80% of defense exports from the UK over the last ten years. Over 18,000 highly skilled jobs are involved.
Currently, the concept aircraft has been put together exclusively by British firms including BAE Systems, Leonardo, MBDA, and Rolls-Royce.
The four companies joined together with the RAF Rapid Capabilities Office to form ‘Team Tempest’ to pursue the opportunity.
The team combines advanced capabilities across four key technology areas:
- advanced combat air systems and integration (BAE Systems);
- advanced power and propulsion systems (Rolls-Royce);
- advanced sensors, electronics and avionics (Leonardo) and
- advanced weapon systems (MBDA).
Early decisions around how to acquire the Tempest will be taken by the end of 2020, followed by final investment decisions to be made in 2025.
The aim is then for a next-generation platform to reach the operational capability by 2035.
In 2015, as France and the UK committed to investing about €1.5 Billion in the development of future unmanned air vehicle demonstrator by 2025, their long-term goal was to field such capability by 2030.
Each side would have supported its technology development and risk reduction studies. In the UK, it was Future Combat Air System Technology Initiative (FCAS-TI).
Under the Tempest program, the British investment in FCAS-TI will exceed the entire amount allocated for the Anglo-French cooperation. Secretary Williamson confirmed the ongoing commitment to FCAS-TI would be more than £2bn of technology investment by 2025 (MOD and industry partners combined).
The resources on the government side are likely to be drawn from the funds initially allocated for the FCAS in 2015, with industry filling the remaining amount.
The introduction of the futuristic fighter plane coincided with the announcement of the U.K. new ‘Combat Air Strategy.’
While the concept fighter plane is in the early technology and concept evaluation, it will feature several advanced key capabilities to enable the platform to remain viable for decades.
These include ‘physical design and reconfigurable, electronic cyber resilient open system architecture designed for growth’. An array of sensors and countermeasures will be employed, using distributed, multi-spectral passive and active electro-optical and RF systems.
The weapons initially considered are the latest types of guided weapons such as the Meteor and SPEAR 3, the aircraft design will feature a modular bay that could carry different payloads and weapons, supporting kinetic, directed energy and non-kinetic effects.
Other future armaments could include hypersonic air launches weapons, connected, cooperative and artificially intelligent weapons (smart swarms) and novel air/air weapons that could be employed in self-protection.
With external weapon stations augmenting the main bay maintaining low observable capability but the platform will also enable the integration of laser weapons and new effectors contained in conformal, low-observable conformal weapon dispensers and payloads, more fuel will also be carried in conformal, low-observable fuel tanks.
A virtual cockpit implementing cutting-edge displays and augmented / virtual reality that customizes displays and enable rapid upgrades.
Scalable autonomy will enable the platform to evolve, from manned configuration utilizing decision aids to reduce the pilot workload to a formation of manned aircraft and optionally unmanned ’wingman’.
Reconfigurable communications will enable the future aircraft to integrate into coalition fully and cooperative network, assuring high bandwidth links with other networked air assets, UAVs, maritime and ground forces.
The Tempest will be a twin-engine aircraft, powered by advanced turbojet engines implementing advanced technologies to be developed by Rolls Royce.
The new engine will be lighter, smaller and more powerful, compared to current turbofans.
The engine will be surrounded by a network of tubes that function as an integrated heat management system, enabling the power plant to operate at higher temperatures.
It will implement a lightweight, aerodynamically optimized fan with high distortion tolerance, lightweight parts made of advanced metal matrix and 3D printed ceramics that would enable temperature and power densities unavailable with past technology.
An embedded starter generator will be able to generate more power at a lower weight, supporting all systems aboard.
