The US Navy has awarded a contract to AgustaWestland Philadelphia (Leonardo ) to produce and deliver additional TH-73A helicopters.

Under the $159.4m contract, the service is ordering the third lot of 36 TH-73A aircraft and initial spares.

It is a firm-fixed-price modification to the previously awarded contract for the US Navy’s Advanced Helicopter Training System (AHTS) programme.

In January last year, Leonardo won a $176m firm-fixed-price contract for the production and delivery of an initial 32 TH-73A helicopters. It also included offering ancillary instructor pilot and maintenance personnel training.

During the same year in November, a $171m contract modification was awarded to the company for the second lot of aircraft, which involved the delivery of another 36 TH-73A helicopters.

With this lot III option, the total number of TH-73A helicopters ordered by the Navy, so far, increases to 104. It has a total requirement for 130 aircraft.

Deliveries of the TH-73A helicopters to the US Navy will run until 2024.

In June this year, Leonardo Helicopters delivered the first TH-73A training helicopters to the US Navy at its facility in Philadelphia, US.

The TH-73A will serve as the first training aircraft and ensure the service has the capacity to train several future student aviators of the US Navy (USN), US Marine Corps (USMC), and US Coast Guard.

It is based on the commercial AW119Kx’s Instrument Flight Rules (IFR)-certified variant.

The aircraft are being manufactured by Leonardo in the US with assembling being performed, via Federal Aviation Administration (FAA) Airworthiness certification, in its FAA Part 21 facility located in Philadelphia, Pennsylvania.
