specially designed and constructed to launch the Space Shuttle vehicle. It is also distinguished as
the site for the launch of both Return-to-Flight missions. Launch Complex 39: Pad B is also
eligible for the NRHP under Criterion C in the area of Engineering. The main components,
including the FSS, the RSS, the Flame Trench, and the concrete hardstand, were specially
designed for the new technologies and rockets of the Apollo Program, and further updated for the
new requirements of the Space Shuttle Program. In particular, the FSS is fitted with a special
hinge that allows the RSS to rotate; the RSS, with the PCR, is designed to fit around the payload
bay of the orbiter. In addition, the Flame Trench is sectioned to provide separate deflectors for
the SRBs and the SSMEs. The Sound Suppression System is a water-based system designed to
protect the orbiter and its payloads from damage caused by acoustical energy reflecting off the
Mobile Launcher Platform during liftoff. LP 39B is of exceptional importance to the Space
Shuttle Program, and because it is less than 50 years in age, Criteria Consideration G applies.
INTEGRITY: Although it has undergone major modifications since the Apollo-era, Launch
Complex 39: Pad B retains its original Space Shuttle Program design and construction. It
continues to convey its historic function as a launch facility, and maintains its integrity of
location, design, setting, materials, workmanship, feeling, and association.
