ADSB Exchange can be a good choice if you want to keep track of the latest military planes. This site allows users to search for planes and display their locations 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 wrote a helpful tip sheet which can help you navigate through 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 is the nonprofit provider of this service. Journalists and investigators may find the platform useful.
The tracker service is completely free. However, you must have the equipment to use it. You need an ADS-B ground transmitter. It takes around 10-20 minutes to configure and install the device. This will increase the ADS-B coverage in your area. C4ADS offers this equipment free of cost to volunteers.
Scramble
Scramble allows you to track any military aircraft that is flying over the United States or Europe using the Scramble military planes tracking tool. Scramble also provides databases for South America's air forces, Africa's, and Asia. The Dutch Aviation Society maintains this website and 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.

Combat is one of the most common uses of scrambling. Military planes can quickly mobilize to combat a threat in a scramble. They are often sent to intercept 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 also tracks private planes and boats that use transponder tech to communicate their location.
There are many other military planes tracking tools available, in addition to Dictator Alert. Some are free and others require programming skills and bulk flight data. ADSB tracking requires high levels of programming knowledge.
Planeflightracker
The Airplane Tracker allows you to view the latest flights of planes in real-time. The tracker displays all information about the aircraft along with a trail on Google maps. It updates every half hour, and you can zoom in or out.
There are many different military aircraft trackers. Some are classified as private, but others are made public. Scramble, for instance, maintains databases on various air forces across the US, Europe Canada, Africa and Asia. Another site, Planeflightracker, specializes in Russian and NATO military aircraft.

Aircraft serial number search
Aircraft Serial Number Search will help you identify any planes that fly over your neighborhood. This website allows the user to search through the serial numbers of military planes, and which countries they're flying over. Joe Baugher, a collector of military serial numbers, founded this site. He also has an impressive collection of Aviation Sites. The ADSB Exchange allows you to track military flights over Europe.
The serial number of an aircraft is unique and can be found near the tail. These numbers are typically 12 inches tall. These serial numbers cannot be modified and are assigned by the manufacturer. These unique numbers are used to identify an aircraft and track their journeys over many years, or between purchases.
