The fiscal year 2018 (FY 2018) National Defense Authorization Act has been signed into law, boosting the US military’s size, adding strategic missile defence requirements, changing rules for buying commercial off-the-shelf goods, and more.
The legislation, signed on 12 December by President Donald Trump, grows US Army active-duty end strength by 7,500 soldiers, from 476,000 authorised last year to 483,500 this year. The US Navy grows from 323,900 active-duty sailors to 327,900, and similarly the US Air Force would grow from 321,000 to 325,100 active-duty airmen. The US Marine Corps would grow from 185,000 to 186,000 active-duty marines.
It calls for expanded US missile defences and requires a Pentagon plan for reaching 104 homeland defence interceptors, known as Ground-Based Interceptors (GBIs), which are launched by the Ground-based Midcourse Defense (GMD) system and are intended to destroy warheads launched on intercontinental ballistic missiles.
