FourFourOne of the most iconic of aircon systems in the world is the Casement Window, built in the 1930s for the US Navy.
It is now a part of a museum in Los Angeles, and can still be seen from the outside of the Pentagon.
A video released last week by the Los Angeles County Museum of Art, in which the Casements is shown in action, was filmed by photographer Michael Lutz and shows a series of shots taken from inside the museum.
One shows the airbrush of the Casings at a time of night, and another shows the windows of the base on display.
One of the earliest examples of a Casement window was built for the United States Navy during the Second World War.
The aircon was originally designed to allow the crew to operate a range of weapons including bombs and torpedoes, but was later extended to include a wide range of other aircraft.
The Casement was designed by the German company Rheinmetall as an effective deterrent against aircraft carriers.
In addition to being a deterrent, it also allowed aircraft to pass through the window without being spotted by enemy radar, and was used by US troops during the Vietnam War.
But despite its success, the Casige has not been used in war.
In its place, the US Army uses an Airborne Weapons Systems (AWS) aircon which is a more modern design that incorporates the same design elements.
The USAF’s Casement windows are much more modern, incorporating both the Casettes aircon and an upgrade of the original aircon that uses a different paint scheme.
The upgrades are made by the Boeing Company.
The Airborne Weapon Systems (AWS) aircans are also more advanced, including the air-cooled design and a larger range of air-to-air missiles.
The US Air Force’s Casements are fitted with an infrared sensor and a laser rangefinder, as well as an electronic warfare system.
The infrared sensor can be used to identify and track targets, as opposed to using radar.
The lasers can be activated remotely or through the aircraft’s autopilot.
A third upgrade, the Advanced Airborne Laser Rangefinder (AALR), can target aircraft with a variety of weapons, including missiles and torpedos.
The AWS aircon is also used for a variety, such as aircraft and drones, which can be deployed at a range from 10km to 40km.
The AALR has been used for several missions, such the targeting of Iraqi drones in 2014 and the targeting and destroying of an Iranian ballistic missile in the last decade.
In 2020, the USAF was forced to abandon its aircon because of concerns over the safety of the missiles.
But the Airborne weapons system is still in use today.
