Salient Characteristics and Specifications for

Accelerometer Calibration at the

846th Test Squadron

13 April 2026

1.0 PURPOSE

The 704th Test Group’s (704 TG) mission is to be the premier provider of unique test and evaluation capabilities relevant to tomorrow’s warfighter through world-class people improving technical excellence, cost-effectiveness, and agility. The 846th Test Squadron (846 TS) is one of the units assigned as part of the 704 TG. The 846 TS’s primary test capability is the Holloman High Speed Test Track (HHSTT) where they utilize rocket powered sled trains to simulate flight like environments and scenarios with the control and recovery of a ground based system.

The 846 TS using customer selected sensors to collect data as sleds traverse the HHSTT on a upcoming mission. The squadron does not have the capability to calibrate these sensors up to customers requested 5 kHz range. This sensor is mission critical for the 846 TS mission support. Any lapsed calibrations will negatively impact the ability of the squadron to collect critical data for a upcoming mission.

Note: These sensors are used to record various data on Rocket Sleds for Guidance System Programs.

Unavailability of this vital asset, due to a lapsed calibration, will impact the Ground Based Strategic Deterrent (GBSD) Sled Test Project.

This requirement includes one calibration to be completed no later than 15 May 2026, and up to four (4) optional calibrations to be exercised no later than 31 Dec 2027 if required. All calibrations must be completed within 30 days after notice to proceed.
