IRIS Dena was a ~1,500-ton Moudge-class frigate & let’s be clear about capabilities. This was a lightly equipped surface combatant with basic hull-mounted sonar, no towed array, limited ASW envelope, and certainly not designed to counter a modern nuclear attack submarine operating at advantage. If a Virginia-class submarine is...

There is a lot of confusion right now about the sinking of the Iranian warship IRIS Dena and the role of the United States submarine in this incident. So let’s understand what most likely happened. First, the attack took place in international waters near Sri Lanka in the Indian Ocean. Second, the submarine involved was most likely a US nuclear powered attack submarine already operating somewhere in the Indian Ocean region. Many analysts believe it could have been operating from the broader operational area around Diego Garcia, a strategic military base used by the United States and the United Kingdom in the Indian Ocean. Unlike conventional submarines, nuclear submarines can stay underwater for months, because they do not need to surface for fuel. The only real limitation is food and crew endurance. So the submarine could easily remain in the region, quietly tracking naval movements. Now here is the timing part. The Iranian warship IRIS Dena had recently visited Visakhapatnam in India to participate in a multinational naval event hosted by the Indian Navy. After the exercise ended, the ship left Indian waters and began sailing west toward the Arabian Sea. If the submarine was tracking it, the most logical moment to strike would be after the ship left the exercise area and entered open international waters. That is when the torpedo strike reportedly happened near Sri Lanka. Now the next question people are asking is whether this was legal. Under the law of naval warfare, if two countries are in an armed conflict, a military vessel of the opposing side becomes a legitimate military target. Warships can be attacked even in international waters. In this case, the target was not a civilian vessel. It was a military warship of the Iranian navy. So from a naval warfare perspective, this kind of strike is generally considered permissible during active hostilities.

🇺🇸🇮🇷 The first submarine kill on a warship in decades happened in silence A Virginia-class submarine tracked Iran's frigate IRIS Dena through the Indian Ocean using passive sonar. One Mark 48 torpedo at 50+ knots. Hit the stern. Ship gone in minutes. 180 crew aboard. Sri Lanka rescued 32 survivors. The sub was never seen, never heard, and slipped back into the deep before anyone knew what happened. This is the kind of warfare Iran has no answer for and no defense against. Source: Combat Wire YT

🚨 The Submarine That Was a Floating Underwater City Russia’s Typhoon-class nuclear submarine was the largest ever built. At 175 meters long and over 48,000 tons submerged, even two Boeing 747s stacked end to end wouldn’t match its length. Designed for long missions, it included crew living areas, a gym, and a swimming pool. Its double hull design increased survivability, even if the outer hull was damaged, the submarine could continue operating. Powered by two nuclear reactors producing around 190 MW each, it had virtually unlimited range and could surface through Arctic ice. All Typhoon-class submarines have now been decommissioned, with the last one, TK‑208 Dmitry Donskoy, retired in 2023. Plans are underway to convert it into a museum ship. A remarkable achievement in naval engineering, unmatched in size and ambition.

WATCH: Türkiye conducted live-fire demonstrations of three domestically developed naval weapons systems during the Sea Wolf-II/2026 exercise in the Antalya Gulf. It was the first time eight guided missiles and a torpedo were fired simultaneously in a single Turkish naval exercise segment, all against real decommissioned surface targets. The ATMACA anti-ship missile was fired from TCG Burgazada, an Ada-class corvette, striking a surface target 102 kilometers away. The target was destroyed. The sea-skimming missile uses indigenous INS/GPS guidance with a terminal seeker, and the demonstration validated its extended-range anti-surface capability in an Eastern Mediterranean setting. The AKYA heavyweight torpedo was fired from TCG Sakarya, a Preveze-class submarine, at a target 10 kilometers away. The torpedo split the target ship in half. It was the first live operational demonstration of Türkiye's indigenous heavyweight torpedo in a major fleet exercise. The HİSAR-D RF naval air defense missile was launched vertically from a MIDLAS system against an air target approaching at 555 km/h. The intercept was successful. The system uses an active RF seeker and dual-pulse motor and is part of Turkey's Çelik Kubbe, Steel Dome, layered naval air defense concept.

🇬🇧 WATCH: A new animation shows a Royal Navy carrier strike group operating with multiple surface combatants and a Type 26 frigate armed with DragonFire laser weapons on both port and starboard sides. The scenario demonstrates a layered defence concept engaging three different threat types simultaneously, highlighting how future British naval task groups could counter drones, missiles, and fast attack threats at sea. This is the direction modern naval warfare is heading.

A narrative of an unjust attack by the United States on the IRIS Dena warship in the Indian Ocean “Hamed Momeneh,” one of the sailors on the Dena warship: This vessel had been sent to the port of Visakhapatnam in India to take part in a naval exercise. While returning home, and as the ship was sailing in international waters of the Indian Ocean, it came under attack. It was around 3:00 to 3:30 a.m. when we were suddenly attacked—an attack that was completely against international maritime laws. It was not a war zone, and we had received no warning. The attack was carried out without warning by a submarine. When the first torpedo hit, all personnel were at their posts, and fortunately at that moment we had no casualties. There were 104 crew members on board, and no one left the ship. Everyone stood their ground until the end. If their aim had only been to damage the ship, they could have targeted other parts, but the main goal was to kill the crew. Even so, we stood firm to the end. For us, the Dena was like the soil of Iran, and leaving it had no meaning. The forces remained with the vessel until 11 pm, after which they were forced to swim for some distance in the ocean to reach areas near the coast of Sri Lanka.

Russia's Typhoon (Akula)-class nuclear submarine. This isn't just a submarine-it's a moving city beneath the ocean. At 175 meters long and over 48,000 tons submerged, it remains the largest submarine ever built. For perspective: even stacking two massive Boeing 747s wouldn't match its length. Inside, the Typhoon had a swimming pool, gym, and full crew living areas. Its enormous size was made possible by a double-hull design with two fully pressurized, parallel hulls-something no other submarine has matched at this scale. That double hull also gave it incredible survivability. Even if the outer hull was damaged, the submarine could continue its mission. Power came from two nuclear reactors, each producing around 190 MW of thermal power, giving it virtually unlimited range and enough strength to surface through Arctic ice.

First Combat Use of Underwater Kamikaze Drones: Russian Kilo class Submarine Disabled in Novorossiysk The Security Service of Ukraine (SSU) has carried out a special operation in the port of Novorossiysk, marking the first-ever combat use of underwater kamikaze drones. During the operation, SBU-operated Sub Sea Baby underwater drones struck a Russian Navy Project 636.3 submarine (Varshavyanka class; NATO designation: Kilo). The explosion caused critical damage, effectively disabling the vessel. The submarine was equipped with four Kalibr cruise missile launchers used by Russia for strikes against Ukrainian territory. The operation was conducted jointly by the SBU’s 13th Main Directorate of Military Counterintelligence and the Ukrainian Navy. A Varshavyanka-class submarine is estimated to cost around USD 400 million. Due to international sanctions, building a comparable submarine today could cost up to USD 500 million. This class is also known as the “Black Hole” because of its low acoustic signature and reduced sonar visibility. The submarine had been stationed in Novorossiysk after earlier Sea Baby surface-drone operations forced Russian naval assets to leave Sevastopol Bay in temporarily occupied Crimea.

🇷🇺🇺🇸🇪🇺🇰🇵 NATO SUNK A RUSSIAN SHIP WITH A TORPEDO!? An investigation into the sinking of the cargo ship Ursa Major in 2024 in the Mediterranean Sea shows the ship was attacked! The Russian ship was carrying important cargo to North Korea, but it was sunk last year. According to the investigation, the ship was carrying two 45-tonne nuclear reactor covers for a nuclear icebreaker of the 10510 project being built. The ship departed from St. Petersburg and was heading to Vladivostok via the Mediterranean Sea. The official cargo included two 45-tonne nuclear reactor covers for a nuclear icebreaker and two German 380-tonne mobile port cranes Liebherr 420, which were to be installed in the port of Vladivostok. On December 22, explosions occurred on the ship, and on the 23rd, it sank. An inspection of the damage showed a hole in the hull with a deformation of the metal inward, which indicates a hit from the outside, not an internal explosion. The investigation suggests that armor-piercing torpedoes were used. -> Who is able to sink ships with torpedoes off the coast of Spain? The answer is simple. The crew was rescued by Spain and the captain of the ship was interrogated there. 1/

"Fascism is a moment in the history of the middle-class, a means by which the middle-class protects itself from the working class." --- Bernardo Bertolucci on 'The Conformist' (1970) Full Excerpt: "'The Conformist' (1970) is first a film about the bourgeoisie, the middle-class, not about fascism. I was speaking about the middle class, and fascism is a moment in the history of the middle-class, a means by which the middle-class protects itself from the working class. Whenever the working class is coming up, up, up, at this moment fascism makes its appearance. In the film there is a fascist and an anti-fascist, but the Professor in Paris, the anti-fascist, is also from the middle-class. We have two faces of the same coin, of the middle-class. One face is fascism, the other is anti-fascism, but not a Marxist anti-fascism, just an idealism. Because he is also in the middle-class, my anti-fascist is not a hero, not a positive man."
