The Pentagon has extended the expiration date of guidance issued in July 2011 outlining when U.S. government agencies may convert intercontinental ballistic missiles into space-launch platforms to haul payloads into orbit.
Inside the Air Force reported last year that Deputy Defense Secretary William Lynn on July 5 signed a directive-type memorandum outlining Pentagon responsibilities and procedures for utilizing excess ballistic missiles for space launch. The document presaged an update to the Defense Department's September 2000 policy on military missions to support space activities.
The new, updated memo incorporates a change made on Jan. 18 that extends the missive's expiration date from Jan. 9, 2012, to Nov. 9, 2012. As ITAF reported last July:
"Acquisition of space launch services using converted excess ballistic missile assets shall ensure required competition at the prime and subcontract level necessary to sustain and enhance the U.S. space launch industry base, and limit the impact on the U.S. space transportation industry," the eight-page document states. "Impact on the U.S. space transportation industry shall consider the broader launch industrial base and viable, established and emerging providers."
The directive codifies practices under which U.S. government agencies -- including the Air Force, the National Reconnaissance Office and NASA -- may use modified ballistic missiles to move satellites to space.
Decommissioned ICBMs may be used for such purposes on a "case-by-case basis," the directive states, requiring the approval of the defense secretary and two other conditions. One condition is "cost savings" to the government when compared to the price tag for space-launch services offered by commercial providers. As for the second condition, the payload slated for launch must support the mission of the sponsoring agency and the "modified excess ballistic missile" must meet the mission's performance, schedule and risk requirements, states the new directive.
These criteria reflect U.S. space transportation policy goals set by former President Bush in National Security Presidential Directive-40, signed on Dec. 4, 2004. "In order to prevent the proliferation of missile technology and to limit the adverse impact of use of excess ballistic missiles on U.S. space transportation capabilities," states the directive, "excess U.S. ballistic missiles shall either be retained for government use or destroyed."
The use of a modified ballistic missile must comply with U.S. obligations under treaties and international agreements, including the Missile Technology Control Regime guidelines, the follow-on Strategic Arms Reduction Treaty and the Intermediate Nuclear Forces Treaty.
