Editing Radial engine (section)

===Tanks===
In the years leading up to World War II, as the need for armored vehicles was realized, designers were faced with the problem of how to power the vehicles, and turned to using aircraft engines, among them radial types. The radial aircraft engines provided greater power-to-weight ratios and were more reliable than conventional inline vehicle engines available at the time.  This reliance had a downside though: if the engines were mounted vertically, as in the [[M3 Lee]] and [[M4 Sherman]], their comparatively large diameter gave the tank a higher silhouette than designs using inline engines.{{Citation needed|date=October 2014}}

The [[Continental R-670]], a 7-cylinder radial aero engine which first flew in 1931, became a widely used tank powerplant, being installed in the [[M1 Combat Car]], [[M2 Light Tank]], [[M3 Stuart]], [[M3 Lee]], and [[Landing Vehicle Tracked|LVT-2 Water Buffalo]].{{Citation needed|date=October 2014}}

The [[Guiberson T-1020]], a 9-cylinder radial diesel aero engine, was used in the [[M1 Combat Car|M1A1E1]], while the [[Wright R-975|Continental R975]] saw service in the [[M4 Sherman]], [[M7 Priest]], [[M18 Hellcat]] [[tank destroyer]], and the [[M44 self propelled howitzer]].{{Citation needed|date=October 2014}}
