AGM-88E Advanced Anti- Radiation Guided Missile (AARGM)

The Advanced Anti- Radiation Guided Missile (AARGM) Project is a Phase III Small Business Innovative Research (SBIR) program to develop and demonstrate a dual- mode guidance section on a HARM airframe. The AARGM Phase III technology demonstration program is designed to demonstrate that a Dual- mode (passive Anti- Radiation Homing (ARH)/ active Millimeter Wave (MMW) radar) missile can engage and destroy enemy air defenses in the event that these systems "shut- down" or employ other countermeasures.

The issue of "shut- down" has been a major shortcoming in the suppression of enemy air defenses (SEAD) element of the offensive counter air mission area for the United States Navy and Air Force. Program objectives are to demonstrate an effective and affordable lethal SEAD capability against mobile, relocatable, or fixed air defense threats even in the presence of emitter shutdown or other Anti- Radiation Missile (ARM) countermeasures. The dual- mode technology being developed in the AARGM program has very high potential to solve the problem of "shut- down" not only in the primary weapon for SEAD, the High Speed Anti- Radiation Missile (HARM), but it could be integrated with many other missile airframes.

AARGM is to be employed in the offensive counter air/suppression of enemy air defenses role in direct support of all the mission areas within the objective force (e.g. strike warfare, amphibious warfare, anti-surface ship warfare, command and control warfare, and information warfare) providing a rapid, organic response to air defense threats ranging from smallscale contingencies to major theater war. The AGM-88E AARGM will be designed to provide a new multi-mode guidance section and modified control section mated with existing HARM propulsion and warhead sections. The new guidance section is designed to have a passive anti-radiation homing receiver and associated antennae, a Global Positioning System/Inertial Navigation System, and an active millimeter wave radar for terminal guidance capability. AARGM is projected to have the capability to transmit terminal data via a weapons impact assessment transmitter to national satellites just before AARGM impacts its target. The Navy intends to incorporate a provision to receive off-board targeting information, via the integrated broadcast system. The AARGM acquisition objective is 1,750 missiles.

The AARGM technology demonstration program is an outgrowth of a Phase I and II competitive SBIR program. Phase I and II SBIR efforts successfully demonstrated the feasibility of a dual- mode seeker to address radar "shut- down" issues. Science and Applied Technology (SAT), Inc. (San Diego, CA), was awarded Phase I and II contracts (FY90- 93) and was subsequently selected for a Phase III demonstration in FY94. Phase III work is being performed by SAT under NAVAIR contract N00019- 94- C- 0078. This contractual effort will continue to be incrementally funded, under program element 0205601N, resulting in a cumulative contract value of $150.4M. From FY93 through FY98, the AARGM program was a Congressionally mandated program which received its funding as an annual Congressional add. Starting in FY99, AARGM received its program funding through the standard DoD budget appropriation process. The FY99 funds added by Congress are being used to perform risk reduction tasks in preparation for a potential Milestone II Decision in FY 2003.

The acquisition strategy for the AARGM Program is based upon U. S. Navy operational requirements; the AARGM program is driven by the conclusion derived from an Analysis of Alternatives for advanced Suppression of Enemy Air Defenses (SEAD) technology. Current acquisition strategy is consistent with the FY98 independent program review forwarded to Congress by SECNAV and the FY99 Authorization Report. The innovative research AARGM demonstration is fully funded and executable and will result in fabrication of research articles and limited flight testing of the AARGM dual mode seeker with moderate risk. The U. S. Navy Project Manager is responsible for Program management and execution. AARGM's acquisition strategy delineates Industry and Government responsibilities. The contract strategy (i. e. software evaluation, control test vehicle development and testing, guided test vehicle development and testing) assigns work package tasks to a primary contractor, Science and Applied Technology (SAT) Corp. The SAT contract is funded on an incremental basis with work scope defined in contract options and contract modification statements of work. Government responsibilities include monitoring, technical assessment and validation of contractor technology development. The AARGM technology demonstration was expected to be completed by the end of FY01.

Developmental and operational testing of the AGM-88E AARGM have not yet been performed. According to the DOT&E the system will potentially face two challenges. First, the test range infrastructure does not exist to adequately assess the full capabilities of the design with regard totarget discrimination. The target sets must emulate the threat system in physical appearance as well as in the electronic environment. DOT&E is working with the Program Manager to develop and fund adequate targets to support testing. The second challenge is the limited number of missiles available during testing. The number of missiles dedicated to testing is reasonable based on the program's total procurement and available model tools; however, if any test event shot suffers a failure, there is little reserve to retest and verify the results.
