The Legion's first space cruiser appeared in Adventure
287. The Legion also used a Mark I in Adventure 330, for
no apparent reason.
The Mark II Cruiser appeared in Adventure 306.
When the Legion graduated to the Mark III, the Mark
II was used by the Legion of Substitute Heroes (Adventure
The venerable Mark III Cruiser served the Legion from
Adventure 309 to 349.
Models existed in a variety of colors, including red,
orange, green, blue, red/yellow, red/white, and pink/white/blue.
Minor design changes were evident from issue to issue.
The baroque Mark IV was only used in Adventure
328 and 329. The three-ship fleet consisted of three colors: red,
blue, and green.
The Mark IV's performance must have been disappointing,
because after using it for only a short time, the Legion went
back to the Mark III.
The Mark V Cruiser had a brief tryout in Adventure
343 (red) and 344 (yellow).
Unfortunately, the Mark V proved too crash-prone, and
the Legion once again returned to the tried-and-true design of
the Mark III.
Beginning in Adventure 350, the Legion finally
found a servicable replacement for its aging fleet of Mark IIIs.
The Mark VI, obviously based on its predecessor, served the Legion
well until Adventure 365.
At least six Mark VIs were seen in service: 3 red,
2 yellow, and 1 blue. Others may have been in action behind the
The Mark VII Cruiser, the fastest and most powerful ship in
the galaxy, debuted in Adventure 366. A fleet of at least
4 Mark VIIs was a gift to the Legion from the United Planets
The Mark VIII cruiser served the Legion from Action
386 through 392, again with minor design changes along the way.
Cruisers of the Mark IX design appeared in Superboy
172 - 183, but this design was no more satisfactory than the Mark
With the advent of the Mark X cruiser, the Legion finally
had a state-of-the-art fleet that was a worthy successor to the
Mark III/Mark VI design. Fully equipped, spacious, and striking
in design, the Mark X served the Legion from Superboy 193
thru LSH (v. 2) 285.
In LSH (v. 2) 285, the Legion received 5 Mark
494 cruisers from Nullport. The Mark 494 was a redesign of the
Mark X, more compact and with better euqipment.
The vessels in the picture above (LSH (v. 2)
285) are obviously not the Mark 494's that appeared
in subsequent issues (below). Certainly, even the resources of
Nullport would not have been able to supply five such advanced
cruisers on short notice. The five ships pictured above are obviously
one- or two-person speeders which Portmaster H'Hrnath lent
to the Legionnaires so that they could return to Earth swiftly.
Undoubtedly, the Legion returned these five speeders to Nullport
when they took delivery of the Mark 494 cruisers.
The Mark XI cruiser, which replaced the Mark 494 in
LSH (v. 2) 307, is basically the same design used by the
Legion today. More compact and more heavily-shielded than the
Mark X or Mark 494, the Mark XI's modular design facilitates mass
production, allowing for easy repair and replacement of damaged
vessels. As hard as the Legion is on its cruisers, this is a definite
