The 5th Bomb Wing (5 BW) is a United States Air Force unit assigned to Air Force Global Strike Command's Eighth Air Force. It is stationed at Minot Air Force Base, North Dakota. The wing is also the host unit at Minot. The 5 BW is one of only two B-52H Stratofortress wings in the United States Air Force, the other being the 2d Bomb Wing at Barksdale Air Force Base, Louisiana.
Its 5th Operations Group is a successor organization of the 5th Group (Composite), one of the 15 original combat air groups formed by the Army before World War II.
On 7 December 1941, the 5th Bombardment Group suffered the loss of B-17 Flying Fortress and B-18 Bolo bombers when the Japanese attacked Pearl Harbor, but it sent two B-17s to search vainly for the Japanese task force. After the attack, the group patrolled the waters off the Hawaiian Islands until November 1942, taking part in the Battle of Midway (3–6 June 1942). Active for over 60 years, the 5 BW was a component wing of Strategic Air Command's heavy bomber deterrent force throughout the Cold War.
A wing is an appendage with a surface that produces lift for flight or propulsion through the atmosphere, or through another gaseous or liquid fluid. A wing is an airfoil, which has a streamlined cross-sectional shape producing a useful lift to drag ratio.
The word "wing" from the Old Norse vængr for many centuries referred mainly to the foremost limbs of birds (in addition to the architectural aisle.) But in recent centuries the word's meaning has extended to include lift producing appendages of insects, bats, pterosaurs, boomerangs, some sail boats and aircraft.
"Wing" can also mean an inverted airfoil on a race car that generates a downward force to increase traction.
Various species of penguins and other flighted or flightless water birds such as auks, cormorants, guillemots, shearwaters, eider and scoter ducks and diving petrels are avid swimmers, and use their wings to propel through water.
A wing's aerodynamic quality is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.
