On the way back to Earth from Pluto's orbit, the technical personnel aboard the Macross discovered that the ship's main cannon could no longer function properly.
The reason the main cannon could not function properly was the inexplicable disappearance of the Super Dimension Navigation System.
There had originally been several energy conduits connecting the warship's main reactor and the main cannon's energy storage units, and those conduits had been linked to the Super Dimension Navigation System.
With the disappearance of the Super Dimension Navigation System, all of those conduit connections had been severed. The main cannon now lacked sufficient backup energy conduits to supply it with power.
Furthermore, the Super Dimension Fortress Macross was made up of separate structural sections. Through transformation, the positions of these sections could be switched, temporarily reconnecting the energy conduits in the severed sections.
Thus, the final inspection result was that the Super Dimension Fortress Macross needed to transform into robot form before it could fire its main cannon.
However, reconnecting the severed sections and changing the positions of the energy conduits would cause problems for the city that had only just been built.
For example, houses, various living facilities, and pipelines would be damaged, creating fairly serious chaos.
Captain Gloval did not want the city, which had only just been settled, to be plunged into chaos again, so he temporarily rejected the suggestion to transform.
For the time being, the Macross could only continue flying back to Earth in warship form.
Meanwhile, Lynn Minmay was preparing to hold a solo concert, but unfortunately, Xiao Shan had a mission that day and could not leave.
That day, in the aircraft carrier hangar, Xiao Shan watched the live broadcast of Lynn Minmay's first concert on the television in the lounge.
After finishing a song, Lynn Minmay
