Some of the reasons Russian President Putin is willing to gamble heavily on gaining control of Crimea include the territory’s strategic geography, and also the heavy militarization of the peninsula and the location of existing strategic assets in Crimea. This post will take a close look at some of those assets using commercial satellite imagery. Be aware that these images are likely more than a month old, since commercial imagery sites are not updated often. They do not represent the rapidly-evolving situation currently on the ground in Crimea.
The first most critical asset is Crimea’s geography, dominating the northern half of the Black Sea. The excellent harbor at Sevastopol has been the home port of the Russian and former Soviet Black Sea Fleet for decades. Ukraine signed a series of long-term agreements with Russia that allow the fleet to continue to use the harbor even though it is on Ukrainian territory. (Click to enlarge)
Zooming in on Crimea, we see the peninsula is populated with strategic assets. The fleet base at Sevastopol is tagged in Cyan. Airbases are tagged in green. S-300 surface to air missile units are tagged in red. Active Ukrainian airbases include Balbek, just north of Sevastopol, with Sukhoi Su-27 and MiG-29 fighters, and Kirovskoye in the east of the country, with MiG-29s. A Ukrainian anti-submarine aviation unit is based at Saky Airbase on the west coast, with Beriev Be-12 seaplanes and Kamov Ka-27 helicopters. The Russian navy bases a squadron of Su-24 anti-ship bombers at Hvardiiske Airbase north of Simferopol International, as well as composite anti-submarine and transport regiments at Kacha Airbase north of Belbek.
Three powerful S-300 SAM units cluster near Sevastopol, defending the fleet base from air attack, with another at Feodosiya on the southeast coast. (Click to enlarge)
Zooming in further on the Sevastopol area, we see the harbor and fleet base to the east, and the Khersones airbase and the Sevastopol Dnepr radar site the west, defended by an S-300 site. The city of Sevastopol itself covers most of the land mass. (Click to enlarge)
Here is a magnified view of the northern side of the fleet harbor, with some of the major units of the Black Sea Fleet. The Slava-class missile cruiser Moskva has heavy anti-ship and anti-aircraft capabilities and while built during the Cold War, is still likely the most powerful naval unit in the Black Sea. During the US-Syrian crisis in 2013, the Moskva was sent to Syrian waters to shadow the US fleet.
The Kerch is an old Kara-class missile cruiser nearing the end of its operational life. Krivak frigates are useful anti-submarine and escort ships. The two Dergach-class corvettes are very fast hovercraft armed with anti-ship missiles. (Click to enlarge)
The Khersones Airbase west of Sevastopol no longer appears to be in use. The big Dnepr space surveillance radar on the western shore was once a major strategic asset for the Soviet Union, as it was built to provide early warning of a nuclear missile attack from Mediterranean-based American fleet ballistic missile submarines. What look like the building’s ‘wings’ are actually two faces of the giant phased array radar. The radar continued to operate after Ukraine took it over in 1991 and provided space surveillance data to Russia in exchange for Russian funding. The site reportedly went off the air in the mid-2000s and appears to be in poor condition now.
The BBC reported on the afternoon of March 2, European time, that Russian troops had surrounded Belbek Airbase. As of the time this image was taken, Belbek hosted at least seven Ukrainian Su-27 and 42 MiG-29 air defense fighters (cloud cover obscured part of the airbase, preventing a complete count). It is unknown how many are actually operational, or whether as of this moment, any of those fighters are still based in Crimea. (Click to enlarge)

I found more MiG-29s at Kirovskoye Airbase in the east of Crimea, sharing the ramp with some An-72 and An-26 transports, and a couple of two-seat L-39 jet trainers. (Click to enlarge)

Besides the Black Sea Fleet, the Russian Navy also has some aviation assets in Crimea, including the 43rd Independent Naval Shturmovik Squadron armed with Su-24 fighter-bombers outfitted with air-launched anti-ship missiles. The squadron is based at Hvardiiske Airbase north of Simferopol International Airport.
Below is a closer view of the active ramp at Hvardiiske Airbase. When I flew into Simferopol in 2005, I was staring out the window as my Tu-134 airliner descended, and was surprised to get a close look at Hvardiiske and a bunch of Su-24s lined up on the tarmac.
Now let’s look at Ukrainian ground-based air defenses in Crimea. I was able to identify four S-300 SAM sites, three defending Sevastopol and one further east near the port of Feodosiya. The BBC is reporting tonight that Russian forces have surrounded a Ukrainian SAM unit in Yevpatoria, but I was unable to find an S-300 site there. It could be the unit had not deployed into firing positions and would be difficult to spot from satellites.
On paper, the S-300 is a very capable anti-aircraft system with a maximum range between 90 and 200km, depending on the missile type, and limited anti-ballistic missile capability. The Ukrainian S-300s are likely to be older models and less capable than the newest versions now being produced in Russia. Given that it is a Russian-designed system, presumably the Russian air force is also aware of and would be able to exploit any weaknesses of the S-300.
Each S-300 site has a long-range search radar (Ukraine uses the NATO-codename ‘CLAM SHELL’ radar, usually mounted on a mast to increase its range against low-flying targets) and a target tracking radar (Ukraine uses the ‘FLAP LID’ radar, either on masts or vehicle-mounted). There are also always several command and generator vehicles at each site. Each site controls a number of Transporter-Erector-Launcher (TEL) vehicles, each of which carries four missiles. A common configuration uses eight TELs for 32 rounds ready to fire.
Below is the S-300 site between Sevastopol Harbor and Kerchenes Airbase. Four of the eight TELs have their canisters raised in firing mode. (Click to enlarge)
This S-300 site is on the coast just southeast of Kerchenes. (Click to enlarge)
Further southeast along the coast is an old S-200 missile site. Ukrainian troops placed an S-300 unit on one of the firing positions of the old S-200 missiles. Below is a wide view showing the layout of the old S-200 site with three groups of six broadly-spaced single launchers. (Click to enlarge)
Below is a close-up of the S-300 unit. Note that *all* of the TELs are in firing position. (Click to enlarge)

Clearly, both Ukraine and Russia consider Crimea a strategic priority, and placed significant assets there to defend the peninsula from external attack by air or sea. The fact that the armed standoff taking place in Crimea is between Russian and Ukrainian ground forces is something of a bitter irony.
