In 1962, the [[United States Marine Corps]] held a competition to choose an assault support helicopter to replace the [[Cessna O-1]] fixed-wing aircraft and the [[HH-43 Huskie|Kaman OH-43D]] helicopter. The winner was the UH-1B, which was already in service with the Army. The helicopter was designated the ''UH-1E'' and modified to meet Marine requirements. The major changes included the use of all-aluminum construction for corrosion resistance,{{#tag:ref|Earlier UH-1s had some magnesium components.|group=N}} radios compatible with Marine Corps ground frequencies, a rotor brake for shipboard use to stop the rotor quickly on shutdown and a roof-mounted rescue hoist.{{Citation needed|date=June 2022}} |

The UH-1E was first flown on 7 October 1963, and deliveries commenced on 21 February 1964; a total of 192 Iroquois of this model were completed.<ref name= "remarkheuy 2016"/> Due to production line realities at Bell, the UH-1E was produced in two versions, both with the same UH-1E designation. The first 34 built were essentially UH-1B airframes with the Lycoming T53-L-11 engine producing 1,100 shp (820 kW).{{Citation needed|date=June 2022}} When Bell switched production to the UH-1C, the UH-1E production benefited from the same changes. The Marine Corps later upgraded UH-1E engines to the Lycoming T53-L-13, which produced 1,400 shp (1,000 kW), after the Army introduced the UH-1M and upgraded their UH-1C helicopters to the same engine. |
