Already, the Ki-M1-1b has been produced by the millions. Within the first month alone, KFY shipped over 2.3 million of the Lamia to CICS-1b, Yui-4d, and Irim ships. Such unprecedented numbers will undoubtedly keep the mecha around for a very long time. The resources used to build millions of Lamia units have drawn some criticism, resulting in the construction of even cheaper mecha (such as the Ki-M1-2a) and the reduction of weapons on the Lamia itself (one WA-3 scalar cannon was removed).
Sadly, over a half-million Lamia were lost in the first battle they were used in, when the enemy deployed a field that hampered spatial distortion. While aimed to disrupt FTL activities, the field also interfered with the distortion-based sublight function of the drive. With no viable way to recover the mecha, there was no choice but to leave them to die. Following the battle, the Lamia were replaced by an updated version, equipped with backup engines.
There are now over 35 billion Lamia M1 in service throughout the Star Army.
