During the Cold War, military bases were built in remote locations to protect strategic assets.
Many of these facilities were designed to withstand attacks and ensure secrecy.
Some were abandoned when they were no longer needed, while others remained in use for decades. In certain cases, old bases have been repurposed for modern military operations.
Reports suggest that Russia may be reviving an underground submarine base in Balaklava, located on the Crimean Peninsula.
Increased Activity
The facility, originally built during the Soviet era, was designed to shelter submarines from aerial and nuclear attacks.
It remained in operation until the early 1990s, when it was decommissioned and turned into a museum.
Satellite images and local sources indicate that the site has seen increased activity in recent months, according to WP.
There are claims that defensive barriers are being installed to protect it from potential attacks. Some reports suggest that Russian naval forces have been using the base for logistical operations.
Others believe it may serve as a repair or resupply station for submarines operating in the Black Sea.
The base was originally constructed to house diesel-electric submarines.
It included reinforced tunnels, storage areas, and living quarters for personnel. Its location, hidden within rocky cliffs, provided natural protection.
The entrance could be sealed off in case of an emergency, allowing submarines to remain secure inside.
Since the start of the war in Ukraine, the Black Sea has been an important battleground. Ukrainian forces have carried out strikes on Russian warships and naval facilities.
The potential reactivation of the Balaklava base could be an attempt to provide additional security for submarines.
Ukrainian intelligence sources have reported construction work at the site, though the full extent of its use remains unclear.
Some experts believe the base could be used to store weapons or launch operations. Others think it may serve as a precautionary measure in response to recent attacks.
