Spoilerizing just in case.

Spoiler for Robotech and SDF Macross:

The SDF-1 (and -2) were destroyed by Khyron's final kamikaze attack in Robotech. In Macross, the SDF-1 survives despite major damage and remains as Earth's main military headquarters. (This is one time I think Robotech improved upon Macross. Without Gloval and the crew making the ultimate sacrifice, the final arc is pretty anti-climactic.)

You're probably thinking of the SDF-3, which was Rick and Lisa's flagship when they went off to explore the galaxy. When their force returned to liberate Earth from the Invid, the SDF-3 didn't materialized with the rest of the fleet. At the end of the series, Scott went off to search for them.

(Rick and Lisa's absence from the fleet really annoyed me as a kid, before I found out the cobbled-together origin of Robotech. To make things worse, they don't even appear in the Shadow Chronicles movie that Harmony Gold produced.)
