Title: UK Type 31 general purpose frigates

BAE unveils potential designs for the Type 31 Frigate | July 28, 2016

Plans to acquire a new class of “more affordable” general purpose vessels at the expense of five Type 26 frigates were announced last year as part of the 2015 Strategic Defence and Security Review.

It is understood that the Type 26 Frigate will primarily support carrier task group operations while the Type 31 is to be deployed for a range of less high-tempo operations.

The original planning assumption for the Royal Navy was for thirteen Type 26 Frigates (eight ASW and five GP), replacing the Type 23 frigate fleet like-for-like.

The two designs are pictured below.

The Cutlass design, pictured above, is a significantly stretched and enhanced derivation of the Al Shamikh-class corvette design and sits at the high end of the cost/capability spectrum.

The Avenger design is a modified Amazonas-class/River-class Batch 2 offshore patrol vessel, similar to the currently in-build OPVs on the Clyde and has been offered to fit the low end of any potential cost and capability options.

UK Type 31 frigates should not be BAE-built, key report recommends | IHS Jane's 360 ( - 30 November 2016
The report, published on 29 November, was written at the behest of government by John Parker, current chairman of mining firm Anglo American, board member of Airbus, and former head of Babcock. Parker's findings were welcomed by Defence Secretary Michael Fallon.

The United Kingdom currently has two major surface combatant programmes that have yet to begin construction: eight advanced Type 26 Global Combat Ships and (instead of five more Type 26s) five smaller and cheaper Type 31s. BAE Systems is set to build the Type 26, and had been expected to also build the spin-off Type 31. However, the report notes that "there is no precedent for building two 'first of class' RN frigates in one location," and concludes that "a separate lead shipyard or alliance appears to be the best way forward for Type 31e to minimise overall risk."

DSEI: Royal Navy Wants to Pitch Type-31e Frigate Design to U.S., Export Market

LONDON — The Royal Navy’s planned Type-31e light frigate will transform the dismal export record of U.K.-based shipbuilders, a senior government minister told attendees at the DSEI exhibition in London. U.K. defense secretary Sir Michael Fallon said that Britain’s shipyards have not built a frigate for another country since the 1970s.

“We’re changing all that”, he declared in a keynote speech on Wednesday.
“This frigate will rock the exports boat and it’s a model for the way we will approach shipbuilding in future.”

The U.S. Navy is among potential overseas customers being courted by U.K. government officials and industry executives for the cut-price combatant, which is intended (in RN guise) to cost no more than $330 million per unit.

Naval Sea Systems Command has issued outline requirements for a multi-mission frigate with an unrefueled range of between 4,500 nautical miles and 6,500 nautical miles at 16 knots, capable of escorting convoys between the United States and Europe. The Type 31e will have a maximum range at the upper end of the U.S. requirement, according to specifications released by the Royal Navy last week.

Among companies vying for the Type 31e design contract is Babcock International, which this week unveiled proposals for a 120-meter, 4,000-ton rapidly reconfigurable warship with multiple mission bays; deck space for eight surface-to-surface missiles, 16 vertical launch cells and a 5-inch gun; a flight deck large enough for a V-22 Osprey tilt-rotor aircraft and hanger for MH-60 Seahawk helicopter; and launch/recovery facilities for unmanned vehicles.

Babcock claims that its Arrowhead 120 design will reduce through-life costs by embedding real-time equipment health monitoring sensors during the build process, allowing information about key systems to be gathered during deployments to inform subsequent maintenance periods.

With transatlantic exports in mind, the company also points to its collaborative venture with Florida-based Eastern Shipbuilding to design a new offshore patrol cutter for the U.S. Coast Guard.

Craig Lockhart, the managing director of Babcock’s Naval Marine business, said that an advisor for U.S. naval procurement had expressed interest in the Arrowhead design, and specifically its innovative ‘iFrigate’ platform monitoring system, at the DSEI event.

Their conversation was a “first glimpse” of NAVSEA’s evolving expectations for a future light frigate, Lockhart told USNI News. “They’ll be getting feedback from the Littoral Combat Ship program and taking all that into consideration.”

The U.K. Ministry of Defence plans to order at least five Type 31e frigates for the Royal Navy, replacing a similar number of aging Type 23 general purpose frigates.

Core requirements include a point defense missile system or close-in weapon system designed to thwart the kind of attack that might be anticipated in maritime constabulary operations, together with medium and small caliber guns capable of engaging fast attack craft, and provision for a hull-mounted sonar.

An open architecture combat system is also mandatory for the Type 31e, which will have a crew of 80 to 100 plus accommodation for an additional 40 mission-specific personnel.

Formal procurement activities in the U.K. are scheduled to start in the first quarter of 2018, followed by a competitive design phase in the second quarter and the award of a design and build contract in the first quarter of 2019. The first of the new ships are planned to enter service in 2023.

In his keynote address, Fallon said: “It’s time to build exportability into our thinking from the off, aligning it with the requirements of international clients, allowing for the open architecture that can plug and play with different bits of capability.

“This is a competition. I want to see great companies competing to lower the cost”, the minister added. Other contenders include BAE Systems, BMT Group and Steller Systems.

The Royal Navy’s new light frigates – like all its complex warships – will be manufactured in the U.K. although units destined for export may be built overseas, perhaps with training or support packages provided from Britain.

Meanwhile, in July this year, BAE Systems started building the first of eight large Type 26 frigates optimised for anti-submarine warfare, designed primarily to escort the U.K.’s ballistic nuclear missile submarines and the new Queen Elizabeth-class aircraft carriers.

The Type 26 program is expected to cost in excess of $10.5 billion, with first-of-class HMS Glasgow due to enter service in the mid-2020s.

Babcock Team 31 Launches Arrowhead 140 Design for UK Type 31e Competition | Navy Recognition ( - 31 May 2018
Babcock Team 31 has today unveiled Arrowhead 140 as its design for the UK Ministry of Defence’s (MOD) new £1.25 billion Type 31e general purpose light frigate programme.

Launching the new platform, ‘Team 31’ – led by Babcock and including fellow industry experts Thales, OMT, BMT, Harland and Wolff and Ferguson Marine – underlined the vessel’s established, ‘at sea’ design baseline which can be developed to meet global requirements.

With UK engineering at its core, and developing OMT’s Iver Huitfeldt hull form currently in-service for the Royal Danish Navy, Arrowhead 140 will lower programme risks through its tried and tested baseline design and is engineered to minimise through-life costs whilst delivering a truly leading edge frigate.
