The Navy Underwater Demolition teams (UDT) in the Korean War played a critical role in shaping the course of this historic conflict. As precursors to modern-day SEAL teams, these elite units executed daring and innovative missions that significantly impacted both military strategies and outcomes.
From their origins under Draper Kauffman’s leadership to notable operations led by George Atcheson, you’ll gain insight into how UDT developed unique training regimes and expanded mission sets throughout World War II and beyond. We’ll explore key operations such as Chromite at Inchon, where UDT men provided invaluable support during amphibious landings; Christmas Eve Raid on Hungnam Waterfront Facilities; and Operation FISHNET – an initiative aimed at crippling North Korea’s food supplies through coastal demolition raids.
As we examine the challenges faced by underwater demolition teams in post-war Navy settings as well as their enduring legacy within today’s SEAL teams, it becomes clear just how integral these specialized units were not only during the Korean War but also for establishing a lasting foundation for future naval special warfare capabilities.
Evolution of Underwater Demolition Teams
The United States Navy established the Underwater Demolition Teams (UDTs) during World War II to clear obstacles for landing craft during amphibious landings.
- 34 UDTs were formed, and Draper Kauffman founded two separate schools for specialized training in underwater demolition techniques.
- UDTs played a crucial role in the Korean War, expanding their mission scope beyond beach clearings to include night coastal demolition raids.
Modern-day Navy SEALs have inherited the legacy of UDTs, with their capacity to execute a variety of assignments such as reconnaissance, unconventional warfare, sabotage activities and combat search & rescue missions.
UDTs in Korea – Expanding Missions Beyond Beach Clearings
In August 1950, the Underwater Demolition Teams (UDTs) began to expand their scope of operations during the Korean War, proving they were more than just beach-clearing experts.
Night Coastal Demolition Raids Targeting Infrastructure
UDTs conducted daring nighttime raids against critical infrastructure like railroad tunnels and bridges to weaken North Korean forces.
Operation with George Atcheson’s Detachment near Yosu
A notable operation led by George Atcheson resulted in the loss of one team member, highlighting the dangers faced by UDTs.
Despite overwhelming odds, UDTs continued to showcase their courage and determination during significant events like amphibious landings at places like Normandy and Pearl Harbor.
The Korean War marked a pivotal juncture in the history of UDTs, spurring the development of present-day SEAL teams that are able to accomplish special missions in multiple settings.

Inchon Landing and Rescue Operations
The Inchon landing, also known as Operation Chromite, was a crucial turning point in the Korean War.
The UDT frogmen played an essential role in this operation by acting as wave-guides for the Marines during their amphibious assault on Wonsan Harbor.
These brave men swam ahead of the landing craft, guiding them through treacherous waters filled with mines and other obstacles to ensure a successful invasion.
One particularly notable rescue mission carried out by the underwater demolition teams involved saving 25 sailors from two minesweepers that had been sunk by North Korean mines.
With little regard for their own safety, these courageous UDT men dove into dangerous waters teeming with enemy forces to bring their fellow servicemen back to safety.
Role as Wave-Guides for Marines at Wonsan Harbor
- The UDTs cleared paths through mine-infested waters for Marine Corps landing craft.
- Frogmen swam ahead of vessels using hand signals or radio communication devices to guide them around potential hazards.
- This vital assistance enabled American troops to successfully carry out one of history’s most daring military operations – securing Inchon and ultimately changing the course of the war in favor of United Nations forces.
Rescuing Sailors from Sunken Minesweepers
- UDT units took part in search and rescue missions during the Korean War.
- When two minesweepers were sunk by North Korean mines, UDT men sprang into action to save their trapped comrades from a watery grave.
- Risking their own lives in hostile waters filled with enemy forces, these fearless frogmen managed to locate and extract 25 sailors who had been stranded on the sinking vessels.
The underwater demolition teams’ contributions during Operation Chromite and other key moments throughout the Korean War are undeniable.
Their heroism, proficiency and tenacity were key in deciding the result of this struggle while also laying a foundation for subsequent cohorts of Navy SEALs to carry out high-stakes operations worldwide.
Destruction of Waterfront Facilities at Hungnam
UDT frogmen set off over 20 tons of explosives to obliterate crucial enemy infrastructure.
This bold action demonstrated their courage and resourcefulness in carrying out high-risk missions behind enemy lines.
The successful completion of this task proved that the UDTs were capable of executing diverse missions.
Participation in Operation FISHNET
In September 1952, UDT men participated in Operation FISHNET, which aimed at reducing North Korea’s food supplies by destroying fishing nets along its coastlines.
These skilled operatives swam through treacherous waters filled with mines and other hazards while avoiding detection from enemy forces.
They successfully cut numerous fishing nets using specialized tools like shears and knives before making a stealthy escape back to friendly territory.
- Evolving Role: The involvement of UDTs in these operations marked a significant shift towards becoming multi-faceted special operators.
- Adaptability: The UDTs displayed remarkable adaptability by mastering new skills and techniques required for these unconventional warfare missions.
Their contributions during the Korean War laid the groundwork for future special operations forces like today’s Navy SEALs.
By demonstrating their capabilities beyond underwater demolitions, they proved that they were an indispensable asset to naval operations.
As a result, these elite units would continue to evolve and play crucial roles in various conflicts around the world.
Evolution from UDTs to Modern-Day SEAL Teams
- The establishment of the Naval Academy’s first “scuba school” at Pearl Harbor marked an important milestone towards developing new capabilities within these elite units.
- In 1961, President John F. Kennedy called for an expansion of America’s special forces capabilities – this led directly to the formation of two dedicated Sea-Air-Land (SEAL) teams under control of regular Navy command structure.
- Building on the heritage of their UDT predecessors, SEALs have since participated in countless missions around the globe – from Vietnam to Afghanistan and beyond.
The evolution of Underwater Demolition Teams into modern-day SEAL teams is a testament to the adaptability and resilience of these elite warriors.
Tracing their roots to WWII, these intrepid soldiers have consistently demonstrated an aptitude for overcoming difficulties and staying ahead of the curve in special operations.
As threats continue to evolve, so too will the capabilities and mission sets of Navy SEALs – ensuring they are always prepared for whatever challenges may come.
