LP-0A (located at 37°50′02″N 75°29′16″W / 37.833959°N 75.4878331°W / 37.833959; -75.4878331 (Wallops Island Launch Pad 0-A)) was first built for the failed Conestoga rocket program.

The pad was reinforced with pilings and features a liquid fueling facility, flame trench, and deluge system for cooling and sound suppression.

[7] On October 28, 2014, an Orbital Systems Antares rocket, flying as mission Cygnus CRS Orb-3, crashed 6 seconds after takeoff and appeared to have done significant damage to the launch pad itself.

In August 2022, Northrop Grumman announced that they plan to transition from the 200-series to the 300-series of Antares, as the Russian invasion of Ukraine in February ended the production of the Russian-designed and Ukrainian-built RD-181 used as the first stage engine.

As a result, LP-0A and surrounding facilities would require moderate renovations in order to support the upgraded rocket's larger first stage to be produced by Firefly Aerospace.

[13] As part of the renovation, Firefly also announced that the facility will become an East Coast launch site of their own Firefly Alpha lifter upon the pad's completion, helping support existing operations from SLC-2W at Vandenberg Space Force Base and future operations at SLC-20 at Cape Canaveral.

LP-0B (located at 37°49′52″N 75°29′29″W / 37.8311576°N 75.4913829°W / 37.8311576; -75.4913829 (Wallops Island Launch Pad 0-B)) became operational in 1999,[24] and was subsequently upgraded in 2003 with the construction of a mobile service tower, which was completed in 2004.

[35] In December 2019, construction was completed and Rocket Lab inaugurated Launch Complex 2 at Mid-Atlantic Regional Spaceport.
