Waypoint Echo

Waypoint Echo is a location in the Commonwealth Located between the Edge of the Glowing Sea and Vault 95, it only becomes active if the Sole Survivor is allied with the Brotherhood of Steel and helps them reactivate Liberty Prime during the quest Liberty Reprimed.

Layout
A small Brotherhood of Steel outpost right at the Edge of the Glowing Sea, consisting of a mobile communications array, a semicircle of sandbag barriers and a lone machine gun turret. It plays a minor role as the Brotherhood's staging area for their search for Liberty Prime's Mark 28 nuclear bombs in the Glowing Sea.

During the quest Liberty Reprimed, the waypoint is garrisoned by Scribe Haylen and two more Brotherhood soldiers. The latter remain there afterward and respawn upon death every couple of in-game days even if the Brotherhood has been destroyed during one of the final main quests.

Loot
T-60 power armor pieces respawn on soldiers here. If one manages to pickpocket or destroy their fusion core (easy to do with the Penetrator perk), their power armor frame can be salvaged as well every couple of in-game days. Note that entering such a frame will be considered stealing.

Appearances
Waypoint Echo appears only in Fallout 4.
