In the late 41st Millennium the various Chapters of the Adeptus Astartes no longer make use of long-range artillery tanks, instead using the Whirlwind Multiple Missile Tank almost exclusively as their ranged artillery support. Although no records are known to exist as proof, it is possible that some Chapters still maintain a cache of Legion Basilisks in their armouries, waiting for the day that they may again be of use to the Astartes.
