The New Medium Helicopter (NMH) is a British military programme to procure a new medium-lift support helicopter to replace several existing helicopters operated by the Royal Air Force and British Army. It is expected the new aircraft will enter service during the late-2020s. After early work on specifications and a down select of contenders, bidding was opened in 2024. The requirement is for a production line and 44 medium helicopters planned to accomplish five specific roles. The helicopter is expected to replace Puma, Huey, and Dauphin helicopters in British service.

A main goal is to bolster medium lift capacity, currently supported dwindling numbers of Puma medium helicopters. They entered service in 1968 with 48 being bought, and 24 were upgraded to HC2 standard in the 2010s, and are planned to be service into the late 2020s while the NMH programme is underway. Part way through a transparency notice was issued, that the remaining Huey's are being replaced by Airbus H145 for the time being.

Background

In the 1967 there was an Anglo-French coöperation on helicopters which resulted in a fleet of 48 Westland Puma, which were Sud Aviation/Aerospatiale SA330;the first was delivered in 1968 and British production was active by 1970. The Westland Puma HC.1 fleet replaced Westland Whirlwind HC.Mk 10 and served with distinction in Rhodesia, Norther Ireland, Belize, the 1st Gulf War, including Operation Granby, Balkans, and humanitarian relief operations globally. However, in the 21st century its performance was found lacking in "Hot and High" conditions as encountered on Operation Herrick in Afghanistan. In the 2010s 24 were upgraded with more powerful engines, and entered service as the Puma HC.2 starting in 2013. [1] The Puma HC.2 fleet is planned to be supported until at least 2028.[2]

A RAF Puma helicopter. Although upgraded in the 2010s, the fleet is on track to have been in service 60+ years.

On 22 March 2021, the Ministry of Defence (MOD) published Defence in a Competitive Age, in which it indicated that it would invest in a new medium-lift helicopter during the mid-2020s.[3] The Defence and Security Industrial Strategy, published at the same time, outlined that to maintain cost-effective access to upgrades and support for the helicopter fleet, the MOD's intention was to consolidate the existing fleet through the replacement of the Royal Air Force's 23 Westland Puma HC2, 3 Bell 412 Griffin and subsequently two other helicopter types, with a New Medium Helicopter (NMH).[4][5] The defence press expect that the two other helicopter types to be replaced are the British Army's fleets of 3 Bell 212 and 6 Airbus AS365 Dauphin.[6][5] In 2022, the MoD said they would purchase up to 44 of the NMH.[7] (Since that time Bell 212 and 412 Huey have already been retired or are in that process)

Despite the MOD at the time having yet to release a formal requirement, Airbus Helicopters, Leonardo and Sikorsky all displayed their proposals to meet the NMH requirement at the DSEI 2021 defence exhibition in September 2021.[6]

In October 2021, the MOD indicated that no final decision had been taken on the method of procurement, but that the expectation was that it will be subject to a competition.[8] A prior information notice was published by the MOD on 11 November 2021, which outlined the scope of the project and the intention to carry out early engagement with potential suppliers. The MOD indicated that it anticipated 36 to 44 new helicopters would be procured, as well as two cockpit flight simulators and one cabin simulator.[9] At this stage the estimated cost of the contract was £1 billion and it was anticipated to run from October 2023 until October 2028.[10]

Programme launch

The MOD published a contract notice on 18 May 2022, officially commencing the competition and confirming the intention to acquire up to 44 aircraft. The contact would also include air and ground crew training as well as in-service technical support and maintenance. The contract would now be worth between £900 million and £1.2 billion. Although no contract start date was indicated, it is specified as running for seven years from the date of award. Invitations to tender were expected to be issued by the MOD by 30 September 2022.[11]

In July 2023, Breaking Defence reported that the MOD had reduced the number of aircraft to be acquired to a maximum of 35.[12] However, the MOD responded denying it had slashed the quantity under consideration, stating "There has been no change to the advertised requirement in the New Medium Helicopter contract notice that was published in May 2022." That tender document called for the acquisition of up to 44 New Medium Helicopters with a total budget of up to £1.2 billion ($1.5 billion). The MOD added that "the second half of the competition will be launched later [in 2023]."[13]

H145 Jupiter has come in as a replacement in Cyprus and Brunei

Moreover The Ministry of Defence (MoD) published a transparency notice of the intended procurement to acquire six Airbus H145M helicopters for Cyprus and Brunei missions. Known as Jupiter HC2 (Helicopter Cargo 2) in UK military service, the helicopters are to be delivered from 2024 along with three years of support for an estimated GBP140 million (USD172 million). The MoD already operates the H145 in the trainer configuration, with seven Jupiter HT1 (Helicopter Training 1) aircraft in use with the UK Military Flight Training System. For the Cyprus mission, the Jupiter HC2s will replace the Airbus Puma HC2s that are now performing search-and-rescue and support duties at Royal Air Force (RAF) Akrotiri as an interim measure following the recent retirement of the Bell 412s. For the Brunei mission, the Jupiter HC2s will also replace Puma HC2s that are now supporting the British Army's training mission following the recent retirement of the Bell 212s.[14][15]

In early 2024, bidding was opened for the program, which will be for about 44 medium lift helicopters with an expected contract by the next year. There is expected to be three major bids: Boeing and Airbus are teaming up to offer the H175M, Leonardo the AW149, and Sikorsky's S-70 (the UH-60 Black Hawk). The helicopters are replacing Puma, Huey, Dauphin helicopters, and expected to fill five specific roles on military and humanitarian mission. In addition, a local or near local production line is also anticipated.[16]

Contenders

As of November 2022, there was four aircraft had been offered by their respective manufacturers to meet the anticipated requirement.[17][18] As of 2024, at the start of bidding it is thought there is three main NMH contenders: the H175M, AW149, and S-70/H-60.[16]

Airbus Helicopters H175M

Airbus Helicopters H175

European multinational company Airbus Helicopters – "a military version of the H175, designated as the H175M"[19][20] Boeing has partnered with Airbus on H175M task force.[21]

Leonardo AW149

Leonardo AW149

Italian based manufacturer Leonardo (with its Anglo-Italian AugustaWestland helicopter subsidary) intends on offering the AW149. It is currently operated by the Royal Thai Army and Egyptian Navy. Leonardo has indicated that it would assemble the AW149 at a new assembly-line at its Yeovil facility in Somerset, England.[22] Leonardo's 31 March 2022 press release confirmed that Yeovil will act as a 'final assembly facility' due to Italy's investment in their main AW189/AW149 production line in Brindisi, Italy.[23] In July 2022 Poland ordered 32 AW149 helicopters with production at Leonardo's PZL Świdnik factory. The contract has a value of $1.85 billion (€1.76 billion).[24][25][26][27][28]

Sikorsky S-70 Black Hawk

Sikorsky UH-60 Black Hawk

Sikorsky highlighted that the Black Hawk was designed as a military helicopter, rather than being a military version of a civilian airframe and that it was combat proven.[20] Entering service in 1979, the Black Hawk is operated by 29 countries, including by the US military which had over 2,000 examples across a range of variants.[29]

Past contenders of interest or down selected after DPQQ

The UH-1Y was one options from Bell, which also considered the V-22 tilt rotor and new 525

Boeing MH-139 Grey Wolf

Boeing MH-139 Grey Wolf

It was thought the American company Boeing might offer the MH-139 Grey Wolf (based on the Leonard AW-139) for the UK New Medium Helicopter (NMH) requirements, which was the winner in 2018 of a US Air Force competition to replace the Vietnam-era Bell UH-1N helicopters. However, Boeing did not confirm this though it acknowledged it was the only helicopter in its portfolio that could meat the UK specs.[49][18][17] In 2023 Airbus welcomed Boeing to their H175M task force.[21] As of 2024 at start of bidding, it is reported that Boeing is partnering with Airbus on the H175M.[16]
