These uniforms are made with the same smartfabric material that is used on the Class A uniforms, The Class B Uniforms are often seen on Space Station Personnel. These uniforms will be seen on the DS9 Personnel in the 24th century arc of the Time Travel Saga When the Enterprise-D is Towed to DS9 by Grace after the Battle of Veridian III was altered to have the Enterprise-D Victorious against the Duras sisters, The Enterprise still loses her secondary hull but Grace tractors the Saucer away from Veridian III just as the Warp Core blows thus preventing the crash. Soran is unaware of Grace's arrival since he beamed down to Veridian III just before Grace was thrown into the Veridian System. Soran's probe does launch but it never makes it to the Veridian Star as it is shot out of the Stars by the Enterprise Saucer.
