Mission Bay Handling System

Making a big difference in operating flexibility

Like most warships, space is at a premium in the Royal Navy’s new Type 26 Global Combat Ship. Onboard systems and stores must use the limited area efficiently – but luckily our latest thinking in handling systems design is making a big difference in operating flexibility.

The Type 26 City Class of anti-submarine warfare frigates will form a globally deployable fleet of multi-mission warships capable of undertaking a wide range of roles from high-intensity warfare to humanitarian assistance.

The ship takes full advantage of modular design and open systems architecture, ensuring it can be easily upgraded as new technology develops. Under current planning assumptions, eight Type 26 ships will be delivered to the Royal Navy with the first due to enter service in the early 2020s.

A closer look at the equipment on board

The advanced power system is a combination of diesel-electric or gas turbine mechanical propulsion drive known as CODLOG. Central to the system is a single Rolls-Royce MT30 gas turbine that produces 36MW of power at 38⁰C. This allows the frigate to reach full power in a matter of minutes.

At cruising speed, or when engaged in anti-submarine operations, the ship will operate four Rolls-Royce MTU diesel generators, producing a total of 11.6MW to power its shaft-wound main motors, eliminating main gearbox noise.

In this ultra-quiet diesel-electric propulsion configuration, the Type 26 – already dubbed the ‘ghost ship’ – will rival the noise signature of the Royal Navy’s Type 23 frigates, widely recognised as the benchmark for anti-submarine warfare and low underwater radiated noise signature.

Integrating our Mission Bay handling system

Rolls-Royce was recently awarded a contract by BAE Systems to supply the mission bay handling system (MBHS) and replenishment equipment for the first three ships of the class.

The Canadian-designed MBHS will also be built in Canada, at the Rolls-Royce Peterborough facility, the centre of excellence for launch and recovery systems design and manufacture.

Rolls-Royce has many years of experience in designing launch and recovery systems (LARS) for anchor handlers and construction vessels. This experience has been brought to bear in designing the innovative MBHS tailored to the unique requirements of the Type 26 platform.

Type 26 MBHS functions

  • Deploy and recover boats and unmanned vessels (UxVs) from both sides of the ship while keeping them under positive control.
  • Reach all areas of the mission bay so boats, UxVs, large components or large boxes can be handled safely at sea.
  • Load and offload containers and containerized mission packages from either side without the aid of a dockside crane.

Resembling its forerunner – the commercial rail-mounted LARS, – the naval variant is a telescopic luffing boom unit. It is mounted on twin rails that run across the width of the Type 26 and its open mission bay, and is designed to be truly multi-purpose.

When launching and recovering small boats, unmanned surface vessels (USV) or unmanned underwater vessels (UUV), a constant tension winch – also part of the system – is used.

Active heave compensation (AHC) can be incorporated into the control system to extend vessel operations in severe weather conditions.

As naval requirements continue to evolve, the Rolls-Royce MBHS is designed to accommodate future upgrades. “We know requirements change rapidly,” says Brian Morrow, Business Development Manager for Naval Handling Systems. “As naval vessels have long service lives, our system will continue to develop and will be adaptable to handle the different payloads we have yet to think of and design. The system will be capable of handling the integrated portable solutions that are now being developed.”


Future flexibility

As naval requirements continue to evolve, the Rolls-Royce MBHS is designed to accommodate future upgrades like iWinch and FutureWave, so that future needs and interoperability with other navies can be maintained.

Rapid change

“We know requirements change rapidly" said Brain Morrow, Business Development Manager for Naval Handling Systems. "As naval vessels have long service lives, our system will continue to develop and will be adaptable to handle the different payloads we have yet to think of and design.

The system will be capable of handling the integrated portable solutions that are now being developed." Rolls-Royce has also designed and developed a semi-automatic LARS system in Canada to launch and recover 9m USVs and manned rigid inflatable boats. It is currently fitted to a frigate. 

“We know requirements change rapidly. As naval vessels have long service lives, our system will continue to develop and will be adaptable to handle the different payloads we have yet to think of and design. The system will be capable of handling the integrated portable solutions that are now being developed.”
