==Manufacturer==
The EMU hardware and accessories (PLSS, helmet, communications cap, and locking rings for the helmet and gloves), is manufactured by [[Hamilton Standard]] (later the [[Hamilton Sundstrand]] division of [[Collins Aerospace]]) in [[Windsor Locks, Connecticut]], while the suit's soft components (the arms of the HUT and the entire LTU) are produced by [[ILC Dover]] (a former division of [[Playtex]]) in [[Frederica, Delaware]]. The two companies, who were rivals during the early days of Apollo for the contract to build the "Block II" (moonwalking) space suit, teamed up in 1974 against the [[David Clark Company]] and [[Garrett AiResearch]] for the EMU development and construction. During Apollo, the ILC Dover-produced A7L used the [[Primary Life Support System|life support backpack]], helmet, and locking rings supplied by Hamilton Standard, but originally, ILC Dover was to just supply the arms and legs of the suit, a similar process that still occurs.

In total 18 EMU suits with PLSS were manufactured; 5 were lost during missions, 1 was lost in ground test, and, as of 2017, 11 remain complete and functional.<ref name=Foot04/>
