ADSB Exchange is an excellent military plane tracker. This website allows you to search for specific planes and see their flight paths on a map. You also have access to a detailed options list. You can also download data from ADSB Exchange using their API, though this usually costs money. Jake Creps has created a helpful tip sheet to help you navigate this site.
Icarus Flights
The Icarus Flights military planes tracking system provides enhanced transparency for military aircraft around the globe. It provides location-based searches as well as historical tracking functions. Center for Advanced Defense Studies (a non-profit) provides this service. There are many features on the platform that could be of use to investigators or journalists.
The tracker can be used for free. You will need the equipment to use the tracker. It requires an ADS-B ground receiver. The device is easy to set up and configure. It takes approximately 10-20 minutes. This will increase the ADS-B coverage in your area. C4ADS will provide the equipment at no cost to volunteers if you are interested.
Scramble
Scramble's military aircraft tracker allows users the ability to track all planes flying over Europe or the United States. Scramble also hosts databases that provide information about the various air forces of South America, Africa, Asia. The Dutch Aviation Society maintains the website. This site also hosts The Soviet Transport Database. Planeflightracker specializes on Russian and NATO-military aircraft. GVA Dictator Alert is another useful website. It compares logs from private ADSB antennas with the list of aircraft used in authoritarian regimes.
One of the most common uses for scrambling is in combat. In a scramble, military planes are quickly mobilized to respond to a threat. They are usually sent to intercept a hostile aircraft.
GVA Dictator Alert
A Swiss journalist started a Twitter bot in order to track planes used for authoritarian regimes. More than 60 departures have been posted so far. He plans to expand his work and include other airports throughout Europe. The tool can also be used to track private boats and jets, which communicate using transponder technology.
Other than the Dictator alert military planes tracker, there are also other military planes recorders. Some of them are free, while others require programming expertise and bulk flight tracking data. ADS-B tracking requires a high level of programming knowledge.
Planeflightracker
You can view all the most recent flights in real time with the Airplane Tracker. You can view all details about each aircraft and a trail on Google Maps. You can zoom in and out, and it updates every half an hour.
There are many types of military plane trackers. Some are private, others are open to the public. Scramble for example has databases about different air force types in the US and Europe, Canada, Africa, Asia, and Canada. Planeflightracker offers information on Russian and NATO military aircraft.
Aircraft serial number search
Aircraft Serial Number Search makes it easy to identify planes flying above your neighborhood. This website allows one to search through the military plane's serial numbers and determine which countries they fly over. This site was founded by a military aircraft serial number enthusiast, Joe Baugher. He also maintains an amazing collection of Aviation Sites. One of his most remarkable assets is the ADSB Exchange. This allows you to track military airplanes over Europe.
The serial number of an aircraft is unique and can be found near the tail. These numbers are usually 12 inches tall. These serial numbers can't be altered and are assigned to manufacturers. These unique numbers are used to identify an aircraft and track their journeys over many years, or between purchases.
