Some interesting photos were shared online by the Polish Ministry of Defense. They show one of the MQ-9 drones of the 52nd Expeditionary Operations Group Detachment 2, the unit operating MQ-9 Reaper drones in Europe, flying over Lask Air Base, Poland, with a brand new pod.
The pod seems to be the one used to house the L3 full-band Signals Intelligence (SIGINT) ISR capability, whose integration with the MQ-9 Reaper was announced during Paris Air Show 2019.
