VIVA – The existence of a black hole remains a terrifying phenomenon. According to NASA, a black hole is an astronomical object with the strongest gravitational pull in the universe, to the extent that nothing, including light, can escape it.
The surface of a black hole called the event horizon, is the boundary beyond which the escape velocity exceeds the speed of light.
The speed of light is the cosmic speed limit, and nothing can surpass it. Within the event horizon of a black hole, matter and radiation are drawn in and can never escape.
However, in this context, the "black hole" mentioned refers not to a space phenomenon but to the latest diesel-electric submarine of Russia named Ufa.

Commencing operations in the ocean in November 2022, Ufa, a Kilo-class submarine, is touted as an advanced non-nuclear stealth submarine, nicknamed "black hole" due to its quietness during underwater missions.
According to the TASS website, the Russian Black Sea and Pacific Fleets possess these Project 636.3 submarines and actively participate in Moscow's special military operations in Ukraine.
The Ufa submarine has a length of 240 feet or 74 meters and weighs over 3,900 tons. It can travel at speeds of up to 20 knots.
Moreover, the Ufa "black hole" is manned by a crew of 52 people and is reported to be able to stay at sea for 45 days with an operational depth of 240-300 meters.
The Ufa "black hole" has an operational range of up to 7,500 miles or approximately 12,070 kilometers. This Kilo-class submarine is armed with Kalibr-PL Cruise Missiles launched from torpedo tubes.
