A Drag Resistant Aerospike is a telescoping outward extension that reduces frontal drag on missiles. For a solid object moving through a fluid or gas, drag is the sum of all the aerodynamic or hydrodynamic forces in the direction of the external fluid flow. ... A missile (British English: miss-isle; U.S. English: missl) is, in general, a projectile—that is, something thrown or otherwise propelled. ...
In 1995 at the 33rd Aerospace Sciences Meeting it was reported that tests were performed at an aerospike-protected missile dome to Mach 6 to obtain quantitative surface pressure and temperature-rise data on the Feasibility of an aerospike for hypersonic missiles.
This not only has a use in space travel but also weapons grade missiles. The Trident missile system uses this to reduce its drag by up to 50 percent. The Trident missile is an intercontinental ballistic missile (ICBM) which is armed with nuclear warheads and is launched from submarines (SSBNs), making it an SLBM. There are 14 active US Ohio class submarines and 4 UK Vanguard class submarines equipped with the two variants of Trident: the initial Trident-I...

Lift-induced drag is only relevant when wings or a lifting body are present, and is therefore usually discussed only in the aviation perspective of drag.
Beyond these two kinds of drag there is a third kind of drag, called wave drag, that occurs when the solid object is moving through the fluid at or near the speed of sound in that fluid.
The overall drag of an object is characterized by a dimensionless number called the drag coefficient, and is calculated using the drag equation.
