Florida Today reports that the Titan IV was launched as scheduled on 22 May 99 at 9:36 UTC, and that payload separation has been confirmed: http://www.flatoday.com/012.htm On the same page, Florida Today also casts doubt on the theory that the payload is Lacrosse: "Over the past weeks and months, analysts had said it was the fourth in a series of $1 billion radar intelligence satellites. Previously, the spacecraft have been known as LACROSSE and VEGA. The current codename isn't known. However, such satellites have needed 66-foot long payload fairings for launch aboard Titan 4B rockets. Today's launch features a 50-foot long fairing, according to the Air Force's Space and Missile Systems Center, Los Angeles Air Force Base. Experts believed a new radar imaging satellite was being launched because the oldest one currently in orbit, deployed in March 1991, probably had reached its life expectancy. This launch would allow for a routine replacement. In addition, the known orbital plane of the aging satellite will make a south-bound pass over Vandenberg during the launch period. But the Air Force on Friday confirmed the rocket would use a 50-foot fairing for the first time. The fairing is the smallest available. What top secret cargo is hidden within the shroud has stumped the military space analysts. Earlier Titan 4 rockets from Vandenberg have been thought to have carried imaging satellites, earlier LACROSSE birds and clusters of ocean surveillance spacecraft. However, those payloads have used 56- and 66-foot fairings. So by speculating, what could it be? Possibilities include a next-generation cluster of ocean surveillance satellites, which in earlier launches also featured secondary payloads and used a 56-foot fairing. By removing the extra cargo and flying the satellites solo, is could yield a 50-foot fairing. Or a "super-secret-who-knows-what" satellite. The Air Force has never flown this Titan 4 configuration before and it is believed by military watchers that the NRO has a few new test platforms floating around. It could even be an SDS-type communications satellite." Ted Molczan
