SYSTEM DESCRIPTION & CONTRIBUTION TO JOINT VISION 2010

The AN/SLY-2(V) Advanced Integrated Electronic Warfare System (AIEWS) is the Navy's next generation shipboard electronic warfare system planned for use with the Aegis Combat System and Integrated Ship Defense Systems. It is a total replacement for the AN/SLQ-32(V) system. Increment 1 of AIEWS will include capability to detect and identify radio frequency emissions, provide precision angle of arrival information to cue hard-kill fire control system sensors, and launch self-protection decoy devices. Increment 2 will include additional capability.

AIEWS is an electronic warfare system for surface combatant ships that supports the Joint Vision 2010 concept of full-dimensional protection, by providing a final layer of self-protection against air threat "leakers" for individual ships, and by assisting other self-protection engagement systems. By ensuring such protection, AIEWS contributes indirectly to the concept of precision engagement, enabling strike operations against targets to be executed from many platforms. By further identifying precise directional measurement of electromagnetic emissions in the tactical area, and making this information available to other units via data links, AIEWS directly contributes to the operational concept of dominant maneuver.

The Navy approved the Operational Requirements Document in April 1997. In November 1997, the Program Executive Officer agreed, that for Increment 1, an OA would be conducted for the initial LRIP decision (FY01), followed by at-sea OT with a partially integrated combat system supporting a second LRIP decision (FY02). It was further agreed to conduct OPEVAL with AIEWS fully integrated with an Aegis Combat System, to support the full production decision in FY04; however, the acquisition decision memorandum from the December 1997 Milestone II review failed to reflect the November agreement.

This activity consisted of defining the T&E program, including the supporting modeling and simulation to support the LRIP and full production decisions, as well as follow-on OT&E of AIEWS. In response to OT community concerns regarding the inadequacies of anti-ship cruise missile simulators, a Test Facilities Implementation Team was chartered to recommend options for T&E resources. The TEMP received in March 1998 was returned to the Navy the following month, and was not approved based on the fundamental disconnect between the program structure (as agreed to by the PEO in November 1997) and the program structure reflected in the language of the Milestone II acquisition decision memorandum. Furthermore, the T&E resource requirements for the TEMP will hinge significantly on the TFIT recommendations, although TFIT deliberations had just begun.

At this time, there are no test results on which to base a performance assessment. The Increment 1 T&E program will examine critical operational effectiveness issues, including situation awareness (the effective and accurate detection, track, and identification of radio frequency emitters); engagement support (effective employment of decoys against anti-ship cruise missiles); tactics; and survivability. In addition, the T&E program will address the full spectrum of critical operational suitability issues: reliability, maintainability, availability, logistic supportability, training, and safety. The TFIT continues to address the issues of how to achieve the following for OT&E:

• Adequate simulation of supersonic, low altitude anti-ship cruise missiles for OT&E.



• Adequate representation of radio frequency emitters at operationally realistic densities.

Until these issues are adequately resolved and the overall program structure reflects the Program Executive Officer agreement as described in the Background Information section, the T&E program will remain unsatisfactory.
