The 2153 test of a prototype Xindi weapon in the Calindra system, observed and sabotaged by Enterprise with the help of Shran's Andorian warship Kumari.
The weapon test at Calindra takes place in the Enterprise episode Proving Ground. The Andorian commander Shran arrives in the Delphic Expanse with the Kumari, offering to help Archer find the Xindi. Together they track the weapon's builders to the Calindra system, where Degra's team is preparing to fire a prototype at a moon.
Archer and Shran pose as members of an Andorian mining consortium to get close. The test damages the moon but the weapon overloads, thanks to interference from Enterprise.
Shran then reveals his real orders: he seizes the prototype for the Andorian Imperial Guard, to be used as a deterrent against Vulcan. Archer forces him to jettison it and it is destroyed. As the Kumari leaves, it quietly sends Enterprise its detailed scans of the weapon.
