Discovering the Brave: The Hrabri-Class Submarine
The Hrabri (Brave) was a remarkable vessel that played a significant role in the early 20th-century naval history of Yugoslavia. But who knew about this submarine’s journey and its impact on the region?
From Design to Deployment: The Birth of Hrabri
The Hrabri, the lead boat of the Hrabri-class submarines, was built for the Kingdom of Serbs, Croats, and Slovenes (Yugoslavia) by the Vickers-Armstrong Naval Yard in the UK. Launched in 1927, its design was based on the British L-class submarine from World War I—a fascinating blend of past and future naval technology.
Armed to the Teeth: The Hrabri’s Arsenal
Imagine a submarine packed with weapons ready for any challenge. That’s what the Hrabri was like, armed with six torpedo tubes, two deck guns, a QF 2-pounder anti-aircraft gun, and even two machine guns.
The Submarine’s Design: A Mix of Innovation and Tradition
Internally, the Hrabri was divided into seven watertight compartments. The first two housed torpedo tubes and reserve torpedoes, while the upper levels contained officer accommodations and 112-cell electric batteries. The control room was beneath the conning tower, with a central pumping station for ballast tank operation.
Adventures in the Adriatic: Hrabri’s Early Years
After extensive sea trials, Hrabri sailed to the Adriatic coast of Yugoslavia in April 1928. Its first few years were filled with adventures and cruises to Mediterranean ports.
Ancient Innovations: Salvaged from Austro-Hungarian Ships
Some of its innovations included gyrocompasses salvaged from former Austro-Hungarian Navy ships and a modified periscope for detecting air attacks. These were just some of the unique features that made Hrabri stand out among other submarines.
A Submarine’s Specifications: Power, Speed, and Range
The Hrabri had an overall length of 72.1 meters, a beam of 7.31 meters, and a surfaced displacement of 975 tons or 1164 tons submerged. Its crew initially consisted of five officers and 42 enlisted men but increased to six officers and 47 by 1941.
Powering the Submarine: Diesel Engines and Electric Motors
The submarine was powered by two Vickers V12 diesel engines, each weighing 33.8 tons and rated at 2,400 brake horsepower. Underwater, it had a range of 200 nautical miles (370 kilometers; 230 miles) at 2 knots.
Life Aboard Hrabri: Crew and Operations
The crew’s work to replace screws that often cracked under stress during rough weather was exhausting. The navy had to stock the boat with spare screws, a testament to the challenges faced by submariners in those days.
Combat Readiness: Torpedoes and Guns
Hrabri was fitted with six bow-mounted 533 mm torpedo tubes and carried twelve Whitehead-Weymouth Mark IV torpedoes. It also had two 102 mm guns, one in each of the mounts forward and aft of the bridge.
Post-World War II: Hrabri’s Final Days
By 1938, the KM (Yugoslav Navy) determined that the Hrabri-class boats were worn out and obsolete. But they remained in service until their capture by Italian forces immediately before the 1941 German-led Axis invasion of Yugoslavia, when they were scrapped.
Remembering Hrabri: Commemoration Events
In April 2013, a commemoration event was held in Tivat to mark the 85th anniversary of Hrabri’s arrival at the Bay of Kotor. Dozens of former Yugoslav submariners attended, honoring the legacy of this brave submarine and its crew.
As we reflect on the history of the Hrabri, it’s clear that this submarine played a significant role in shaping naval strategies and operations during its time. Its story is a reminder of the dedication and innovation required to navigate the challenges of the early 20th century.
