Elsa Pataky and Chris Hemsworth are married. This is the second movie they've collaborated on after 12 Strong (2018).
The Platform is loosely based upon the SBX-1 or Sea-Based X-band Radar, which is a mobile floating early warning radar platform designed to track incoming missile attacks and direct outbound Anti-ICBM or ABM Interceptor Missiles and is usually stationed at Adak Island in Alaska. Although in real life the platform is not armed with missiles or any other weapons and is not operated by the military, the radar systems are operated by civilian employees of the Department of Defense's Missile Defense Agency and the vessel itself is operated by the Navy's Military Sealift Command, which is staffed with civilian sailors called Merchant Mariners.
An Easter egg of sorts - between the ending credits and the detailed credits the movie continues with a nine second shot of the TV salesman (Chris Hemsworth) relaxing in a mechanical massage chair after all the excitement of the afternoon.
In the film the United States only has two launch sites aimed at intercepting nuclear warhead launches: Fort Greely in Alaska and the remote launch platform at sea and acts as if they are the only two facilities capable of defending against a missile attack. In real life the United States has a number of sites for ballistic missile defense (BMD), the U.S. Army has two facilities: Fort Greely is one of them and is part of the United States Army's Ground-Based Midcourse Defense system which uses the Ground-Based Interceptor anti-ballistic missile combined with early-warning radar stations around the world to detect, intercept and destroy long-range ICBM's, the other Interceptor missile site is at Vandenburg Space Force Base in California. In addition to these missile bases the Army also has the Terminal High Altitude Area Defense (THAAD) program, which consists of land-based mobile surface-to-air missile platforms like the MIM-104 Patriot Missile battery, which provides defense against short to medium-range ballistic missiles in their terminal phase.
The United States other primary BMD capabilities are provided by the U.S. Navy, which operates the Aegis Ballistic Missile Defense System along with the Department of Defense (DoD). This system consists of two parts, the first being the Navy's fleet of nine active Ticonderoga-class guided missile cruisers and 74 Arleigh Burke-class guided missile destroyers (with 20 more planned), these warships are equipped with the Aegis Combat System, an electronic warfare platform which uses computers and radar to track & intercept guided missiles. The Aegis system employs the AN/SPY-1 fire control radar combined with SM-3 and SM-6 missiles which are designed to intercept and destroy both cruise & ballistic missiles. The second part of the Aegis BMD system consists of three land base facilities, operated in conjunction with the DoD's Missile Defense Agency, called Aegis Ashore facilities. These facilities employ the same AN/SPY-1 radar and SM-3 missiles used on the Navy's warships, the first facility was built in Deveselu, Romania and became operational in 2016, the second in Redzikowo, Poland and became operation in 2024 and the third facility is under construction in Guam and is planned to by operational by 2026.
