From today's featured articleProject E was a Cold War arrangement under which the United States provided the United Kingdom with nuclear weapons for the Royal Air Force (RAF). It was later expanded to provide warheads to the British Army, and there was a maritime version known as Project N that provided nuclear depth bombs. US personnel retained custody of the weapons, and handled their storage, maintenance and readiness. The first bombers equipped with Project E weapons were Canberras (example pictured). Due to the operational restrictions, and the loss of independence of the British nuclear deterrent, Project E bombs were phased out in the strategic role in 1962, although they still equipped tactical bombers, and were used on the Thor missiles operated by the RAF from 1959 to 1963 under Project Emily. The British Army acquired Project E warheads for its Corporal, Honest John and Lance missiles, and its artillery pieces. The last Project E weapons were withdrawn from service in 1992.

From today's featured list
The National Historic Landmarks in Indiana represent Indiana's history from the Native American era to its early European settlers and motor racing. There are 42 National Historic Landmarks (NHLs) in the state, which are located in 23 of its 92 counties. The National Historic Landmark Program is administered by the National Park Service, a branch of the Department of the Interior. The National Park Service determines which properties meet NHL criteria and makes nomination recommendations after an owner notification process. All NHLs are also included on the National Register of Historic Places, a list of historic properties that the National Park Service deems to be worthy of preservation. Marion County, the location of the state capital Indianapolis, has the most NHLs, with ten, followed by Bartholomew County with seven and Jefferson County with four. Eight Historic Landmarks in Indiana are more specifically designated National Historic Landmark Districts, meaning that they cover a large area rather than a single building. The Lanier Mansion (pictured) and Charles L. Shrewsbury House are within the boundaries of the Madison Historic District. (Full list...)
