This follows the first test firing ont he 9th of may, which interestingly was not mentioned widely, however there appeared to be a slight glitch with that firing.
"MBDA’s Meteor Multinational Project Director, Dave Armstrong, said: “These live missile air launches represent a huge achievement as they represent the earliest ever flights of a new missile with solid fuel ramjet technology and have been completed in just over three years from contract let. A minor glitch was observed during the first missile firing with the missile failing to transition to the sustain phase of flight and therefore continuing over the pre-determined flight time under boost impulse, gradually decelerating through the flight. The source of this failure was quickly identified and a modification made which was subsequently proven during the second firing with the missile successfully transitioning from the boost to the sustain phase of flight and completing a series of post-transition manoeuvres”."
