The Defense Research and Development Organization (DRDO) and the Warship Design Bureau of the Indian Navy are collaborating on Project 76, a next-generation diesel-electric attack submarine program. The project aims to procure six submarines with a displacement of 4000 tons, featuring air-independent propulsion and 80% indigenous materials. Authored by Soham for the Geostrata. What are the implications of this project for India's naval modernization and self-reliance in defense production?

As one of the many dedicated individuals who have served in the United States Navy, I am proud to have spent over three decades protecting our nation. One of my most rewarding assignments was serving on a nuclear-powered attack submarine. This article offers a glimpse into the challenging and fulfilling world of the hard-working men and women who serve in the World's Greatest Navy. Check it out!

Type 95 Depth Charge: Japan's WWII Anti-Submarine Weapon The Type 95 depth charge was a key anti-submarine weapon used by the Imperial Japanese Navy during World War II. Developed in the mid-1930s, it featured a cylindrical design, measuring about 600 mm in length and 350 mm in diameter, and weighed approximately 150 kg, with 100 kg of TNT or a similar explosive. Operation It operated using a hydrostatic pressure principle, where a depth-setting mechanism allowed for precise detonation depths. As the charge sank, increasing water pressure triggered a diaphragm, which set off the explosive at the predetermined depth. Deployment The Type 95 could be deployed from ships, aircraft, and coastal installations. Ships used racks and launchers to deploy multiple charges, creating patterns to maximize damage to enemy submarines. Effectiveness and Limitations While effective, the Type 95's success depended on accurate depth settings and submarine detection. Advances in submarine technology, like stronger hulls and deeper diving, gradually reduced its effectiveness, leading to ongoing improvements in anti-submarine weaponry. Legacy The Type 95 depth charge exemplifies wartime innovation and the tactical focus on anti-submarine measures by the Imperial Japanese Navy, marking an important phase in the evolution of Japan naval warfare. #japan #history #ww2 #eod #maritime #EOKHUB

#Corrosion costs the DoD billions of dollars annually and heavily impacts the availability of defense assets to carry out their missions. SERDP and the U.S. Naval Research Laboratory are working together to predict coating and lifetime performance to lower the impact of corrosion mitigation and maintenance activities on the environment. A combined model of real-world fatigue and corrosion damage for DoD assets does not exist – yet. Dr. Christine Sanders and her SERDP project team are generating a model to predict maintenance based on accumulated damage, enabling maintenance cycles to be performed only when necessary. Successful implementation will reduce inspection costs and unnecessary labor. Learn more about our efforts from DSIAC's latest Journal issue: https://bit.ly/4bxuYZp

This #SerdpEstcpWebinar will focus on research efforts to develop protective and environmentally friendly aircraft coatings for DoD ships and aircrafts. Speakers from U.S. Naval Research Laboratory and Naval Air Warfare Center, Aircraft Division (NAWCAD) will discuss the use of organosilane polymers in topcoats and the development of aluminum-rich primers. https://bit.ly/4dB4nvt Protecting defense assets from deterioration by corrosion and wear is critical to maintaining readiness and safety, but many coatings systems have significant environmental effects. This webinar will cover alternatives that SERDP and ESTCP are funding to replace coatings that have environmental and health impacts.

The era of large surface warships, particularly aircraft carriers, as primary tools of naval power projection is facing significant challenges due to the rise of anti-access/area-denial (A2/AD) capabilities, particularly from China. https://lnkd.in/er7XHaRG

USS Delaware Pioneers UUV Deployment The Virginia-class Block III fast-attack submarine, USS Delaware (SSN-791), continues to set new benchmarks in naval warfare technology. Commissioned in April 2022 under unique circumstances, #SSN-791 was the first U.S. Naval warship to be commissioned while submerged due to the COVID-19 pandemic. This year, #USS Delaware will deploy a torpedo-tube launch-and-recovery (TTL&R) uncrewed underwater vehicle (#UUV) in the European theater, marking the first operational use of this capability. This milestone will see the REMUS 600, known as the "Yellow Moray," enhance mission capabilities, including the defense of critical undersea infrastructure. The REMUS 600, capable of semi-autonomous operation and deep-sea missions, signifies a leap in seabed warfare. With the ability to defend and potentially counter threats to #undersea cables and pipelines, this technology is set to redefine the #strategic landscape of underwater operations. Kudos to the innovative minds and skilled hands driving this mission forward. The silent service is making waves—literally and figuratively! #NavyInnovation #UnderwaterWarfare #USSDelaware #DefenseTech #SeabedWarfare #UUV #MilitaryInnovation https://lnkd.in/d9BuxChD

NAVAL GROUP delivered, January 12, 2024, the #Humaitá, a #Scorpène submarine to the Brazilian navy 🇨🇵 🇧🇷 ⚓💪‼️ Under the sweltering heat of the Carioca summer, the #Humaità, second of the four conventional submarines Scorpène (NAVAL GROUP) ordered by Brasilia in 2008, leaves on January 12 for a first operational mission of two weeks. At the heart of the giant naval base, out of land in fifteen years, the ship has just been delivered with great pomp to the Brazilian Navy. The #Humaitá (S-41) is a submarine of the Brazilian Navy #Riachuelo class, derived from the #Scorpène class. #Riachuelo class ships have a higher length, tonnage and carrying capacity than the original French ships. The Brazilian version is 71.62 meters long and a displacement of 1,870 tons, higher than the 66.4 meters and 1,717 tons of #Scorpène. The #Riachuelo class was developed as an intermediate phase for the preparation of the SN Álvaro Alberto (SN-10), the first nuclear-powered submarine in the southern hemisphere, technology that is now mastered by the Brazilian navy and will be the seventh world navy to implement this type of ship. #Submarine #France #Marine

Superb article in CIMSEC by R. Robinson Harris, containing the following quote by Dmitry Filipoff, “…no other service needs to be more invested in tactical superiority and solid warfighting doctrine than navies. If a carrier strike group falls prey to a single missile salvo, that’s about seven thousand lives and $20 billion dollars that is lost in a matter of minutes. By comparison, those numbers would get you about 2,000 tanks, but there is no plausible combat scenario where two thousand tanks are destroyed in a couple minutes. Modern naval warfare is an absolutely brutal form of combat, and because of that, nobody stands to lose so much so quickly from their tactical shortfalls than navies. In naval warfare especially, tactical shortfalls can rapidly escalate into strategic liabilities…” Solid thinking (very unusual in naval circles), cogently argued and well evidenced. Instead of regurgitating 19th and 20th Century naval fallacies, perhaps naval leaders should take heed and spend a little more time on their warfighting doctrine.
