Northrop Grumman has received a $1.5-billion contract to deliver E-2D Advanced Hawkeye aircraft to the US Navy and Japan.
A recent US Department of Defense (DoD) announcement states that the company will produce nine new Hawkeyes: four for the navy and five for Tokyo.
It will also provide associated support services to both customers.
Most work for the contract will be performed in Florida, with an estimated completion date of March 2029.
In 2023, the US State Department approved the foreign military sale to Japan of five E-2D Hawkeyes and related equipment for $1.4 billion.
But the deal recently announced by the US DoD indicated that Tokyo will only pay about half of the estimated amount, or $766.6 million.
No specific reason was provided for the apparent cost reduction.
