What ever happened to SHERPA and all the cubesats that it was planned to deploy? I believe there was supposed to be room for both, and I thought the whole thing had been ready and waiting for launch for a while.
The 2015 SHERPA mission addresses the limitations of current launch configurations by maximizing the number of payloads integrated to the structure. The SHERPA concept is well suited to support small spacecraft that range from CubeSats to 300 kg minisatellites. By developing unique adapters for the standard ports, Spaceflight has enabled many different sizes of spacecraft to deploy from SHERPA, including the DARPA eXCITe microsatellite, built by NovaWurks Inc. of Alamitos, CA
(NovaWurks is a wholly owned subsidiary of Spaceflight Industries, Inc., Seattle)and two BlackSky Global Pathfinder satellites. Future planned configurations involve multiple SHERPA rings on a single launch, as well as support for much larger spacecraft on the forward section of the SHERPA ring.
NOTE: It now seems that NovaWurks is now a privately held, autonomous company and not a subsidiary as the block quote suggested at the time it was published.
