Maritime patrol is the task of monitoring areas of water. Generally conducted by military and law enforcement agencies, maritime patrol is usually aimed at identifying human activities.
Peacetime patrols are important for interdiction of criminal activities and for ensuring legal use of waters.
Maritime patrols can be conducted by surface ships and submarines, Maritime Surveillance Aircraft (MSA) and other aerial vehicles, and even by satellites. Human spotting remains an important part of detecting activity, creates deterrence and recently vast electronic systems are used to be more accurate information and reducing the workload of mission operators.
The Q400 is 6.83 m (22.4 ft) longer than the −300
The Series 400 introduced an even longer airframe that was stretched
6.83 metres (22.4 ft) over the Series 300 (10.26 metres (33.7 ft) over the Series 100/200), has a larger, stouter T-tail and has a passenger
capacity of 68–90. The Series 400 uses Pratt & Whitney Canada PW150A engines rated at 4,850 shp (3,620 kW). The aircraft has a cruise speed
of 360 knots (667 km/h), which is 60–90 knots (111166 km/h) higher than its predecessors. The maximum operating altitude is 25,000 ft (7,600 m) for the standard version, although a version with drop-down oxygen masks is offered, which increases maximum operating altitude to 27,000 ft (8,200 m). Between its service entry in 2000 and the 2018 sale to Longview/Viking, 585 have been delivered at a rate of 30-35 per year.
By 2017, the Q400 aircraft had logged 7 million flight hours with 60 operators and transported over 400 million passengers with a dispatch reliability over 99.5%. By July 2018, 844 Dash 8s were in airline service: 143 Series 100 with 35 operators, 42 Series 200 with 16 operators, 151 Series 300 with 32 operators and 508 Q400s. By then, 56 orders were in backlog.

ST Airborne Systems first developed (under the name SSC Airborne System) an airborne remote sensing system for the Swedish Coast Guard in
the 70’s. Following a number of successful deliveries in Europe, in the late 90’s the MSS 5000 version of the system was developed. This was
first taken into operation in Norway in 1998 (with installation performed by Bromma Air Maintenance), after which followed several installations for Coast Guard, Air Force and Navy customers in Sweden, Poland, Greece, USA and Portugal among others.
The first MSS 6000 system was taken into operation in Canada in 2006 installed on board a Dash 8 aircraft. Until today more than 20 MSS 6000
systems have been delivered to customers around the world. The latest MSS 6000 version is operated by the Finnish Border Guard and includes
among other things two identical operator consoles and an integrated search radar.
Today ST Airborne Systems offers the MSS 7000 which is based on the earlier MSS versions and the collected experiences from deliveries to
coast guard customers in more than twenty countries around the world. The first MSS 7000 system is today in operation on board a Beech King
Air 350 for the Estonian Border Guard.
Some of the new features of MSS 7000 are:
