Qatar’s government has finalised an order for 28 NH Industries NH90 military helicopters that are scheduled to be delivered between 2022 and 2025.

Italian aerospace group Leonardo – which acts as overall prime contractor for the deal valued at more than €3 billion ($3.4 billion) – says that it has booked the order to its backlog and received an advance payment from the Gulf state.

The contract covers provision of 12 NH90 NFH naval helicopters, 16 TTH troop transports, support services, training and certain infrastructure.

Leonardo says the programme could be extended in future “with the addition of six plus six units in a mix of TTH and NFH variants”.

The Rome-based group will assemble and deliver the 12 NFH naval helicopters from its facility in Venice, while Airbus Helicopters will be responsible for the final assembly of the 16 TTH transports.

NH Industries is jointly owned by Airbus Helicopters, Leonardo and Fokker.

Leonardo says that its part of the support and training deal – for the 12 NFH naval helicopters – spans an eight-year period.
