ELECTRONIC WARFARE TRAINING AND TEST AIRCRAFT (EWTTA) AIRCRAFT CONFIGURATION REQUIREMENTS

This attachment identifies the basic aircraft configuration requirements, and aircraft mission system performance thresholds and desired capabilities. Options 1 through 4represent additional capability that is desired but is not part of the basic aircraft configuration requirement. These options may be purchased upon funding availability. Thresholds are defined as specific minimum capabilities which must be met or exceeded. Desired capabilities present a performance level the government would like to attain. The contractor is encouraged to balance desired capability to achieve overall effectiveness.

Effectiveness is considered to be the ability to screen two 15m2 inbound aircraft at a minimum of 100 NM from target air search radar to theoretical burn through range utilizing a 1-6KW Enterprise Resource Planning (ERP) environment within the beamwidth delineated below.

There will be two (2) aircraft required – one (1) based on the east coast and one (1) based on the west coast. There will be a minimum of 490 combined east and west coast flight hours guaranteed.

BASIC AIRCRAFT CONFIGURATION: (minimum requirements) Each Contractor Furnished aircraft shall:

· Operate under FAA Part 135.

· Part 135 maintenance supported with FAA Supplemental Type Certificate (STC) for modifications.

· Have the capability to fly from California to Hawaii with full mission equipment and crew aboard (Desired) or independent shipping of mission equipment and/or personnel at contractor's expense (Threshold). Near polar routing from PACNORWEST and/or in-flight refueling, at contractor's expense, is acceptable.

· A minimum altitude of 6,700 feet is required to achieve acceptable line of site range to surface vessel radar for conducting SOJ missions. (Threshold);
