Das habe ich in einer Pressemitteilung von Aerodata Braunschweig vom Januar 2016 gefunden:
Maritime Patrol Aircraft for Pakistan Navy
Aerodata has been contracted by Rheinland Air Service to deliver its mission system AeroMission® for two ATR-72 aircraft.
These aircraft are already owned by the Pakistan Navy and will be modified from the current transport configuration to a special mission role. Aerodata’s contract with Rheinland Air Service includes all system integration activities as well as the engineering tasks required to
convert the ATR-72 aircraft into a maritime patrol configuration.
The modified ATR-72 aircraft will be capable to perform both above and under water maritime surveillance and real time data
relay being equipped with a high performance sensor suite.
Rheinland Air Service as the prime contractor of the Pakistan Navy will perform the installation of AeroMission® and all sensors at its facility in Mönchengladbach.
In Kurzform: Aerodata modifiziert im Auftrag von RAS am Standort Mönchengladbach zwei ATR-72 der Pakistanischen Marine für die Seeüberwachung.
Die eine ist die schon gezeigte "79", MSN 788 ex A2-ABS, die andere müsste die "78" MSN 712 ex EC-JAH sein.
