ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.

Space Force has cataloged LINK (the Swift reboost spacecraft) in a 362 x 392 km x 20.6 deg orbit, confirming successful launch. TLEs consistent with the launch NOTAM areas
Launch - July 3, at 8:36 p.m. UTC+12 (4:36 a.m. EDT)
Northrop Grumman's Stargazer aircraft took off from Kwajalein Atoll in the South Pacific Ocean, climbed to about 40,000 feet, and dropped a Pegasus XL rocket carrying Katalyst Space's LINK robotic...
Weather Delays Launch of Mission to Boost NASA’s Swift
The launch of Katalyst Space’s robotic servicing spacecraft LINK, designed to boost the orbit of NASA’s Neil Gehrels Swift Observatory, was postponed again Wednesday due to unfavorable weather conditions. The next launch attempt is targeted...
Why? I posted to the discussion of the Mission/Addon to keep it relevant. If I posted over under the live missions heading, it may get lost to someone following the addon and updates to the scenario situation.
Launch of Mission to Boost NASA’s Swift Scrubs Due to Weather

I think you are an hour early unless the TLE for Swift has changed a bunch, I'm seeing about 11:25-11:35 as a rabbit chase and about 1200 UTC Swift flying right over the warning box.
I don't have any insider information other than having been station there and it is that time of the year and Kwajalein is on the inter-tropical convergent zone. Thunderstorms daily with the humidity. Today's snapshot
From the NASA Swift Boost Mission Page:
A mission to raise the orbit of NASA’s Neil Gehrels Swift Observatory is poised for launch no earlier than Tuesday, June 30, 6:23 a.m. EDT (10:23 p.m. UTC+12), from Kwajalein Atoll, part of the Republic of the Marshall Islands in the South Pacific Ocean.
So far, I have not had success with the capture of Swift.
I can get within about about 500 meters but after the RCS fuel is gone, I can't get any closer with the ions.
N140SC arrived in Kwajalein on the 25th.
Based on the latest HYDROPAC 1814/26, looks like launch has slipped to NET June 30.

So it keeps getting more confusing, here is what Celestrak has put out. Johnathan has change the above link to just NTS-3 and USA-554.
Perhaps closer to the graphic by ULA with the two ESPA payload rings. Debris would be consistent with the adapter ring between them.
I'm betting the NTS-3/ESPA ring mounted to the cradle and just the GSSAP sat's were each released individually from the cradle.
I wonder if they didn't just mount onto the two sets of rails?
Jonathan McDowell has posted that the other payloads were GSSAP (Hornet) 7 & 8 (est 650-700kg each)
