Story Sunday: Panjandrum Weapon
The Great Panjandrum at Westward Ho!
Wacky WW2-Era Failed Weapon
In 1941, the Government of the United Kingdom established a temporary wartime body called the Department of Miscellaneous Weapons Development (DMWD) to find new and unconventional ways to kill the enemy. Efforts from this department led to such useful inventions such as the Hedgehog anti-submarine weapon and Squid anti-submarine mortar, as well as the Holman Projector, an anti-aircraft rocket battery—and a system of degaussing used to protect ships against magnetic mines. It also led to the invention of the bouncing bomb that could skip across water to avoid torpedo nets and was used in the very successful Dambusters Raid of 1943. Above all, it played an important role in developing parts of the Mulberry Harbour used in the D-Day landings.
Despite these successes, not all of the DMWD’s projects were fruitful. An attempt to conceal the River Thames from German bombers, by covering it with soot, failed due to the effects of wind and tides, although it did cause some confusion when the coal-covered waters were mistaken for [a] tarmac during blackouts. The most disastrous project, however, was the Panjandrum. With a name inspired by a character in a nonsensical piece of prose from the 18th-century British dramatist Samuel Foote, the Great Panjandrum was doomed from inception. Constructed as a pair of large wheels, each approximately 10 feet in diameter, it featured a central steel drum carrying over a ton of explosives. Around the rims of the wheels were cordite rocket charges, designed to spin the entire device, propelling it towards the concrete beach defenses along the French coast with the intent of creating a substantial breach. The designers estimated that a fully loaded, 1,800-kg Panjandrum could reach speeds of around 60 mph (100 km/h), with enough momentum to crash through any obstacles between its launch point and target.
Trials began with only a handful of cordite rockets attached to the wheels and the payload was simulated by an equivalent weight of sand. The rockets were ignited and the Panjandrum catapulted itself forward, out of the landing craft used as a launchpad […] a fair distance up the beach. However, a number of rockets on one of the wheels failed, causing the weapon to careen off course. Despite several further attempts with more rockets, the Panjandrum consistently lost control before reaching the end of the beach.

The USS Harmon was a U.S. Navy Buckley class destroyer escort named after Leonard Roy Harmon, a Mess Attendant (Messman) First Class that served aboard the USS San Francisco. It was the first U.S. warship to be named after a Black American. It was launched July 25, 1943, by Bethlehem Steel Company in Quincy, MA, sponsored by Harmon’s mother and, seventy-seven years ago, today, it was commissioned. She spent nearly a year serving as an escort ship near New Caledonia. After a short period at Pearl Harbor, she joined the Luzon Reinforcement Group. By March 1945, she was an escort and an anti-submarine screen off Iwo Jima. She returned to Pearl Harbor for training, then to Mare Island for a weapons upgrade and, when the war was over, she conducted training operations with submarines.

Decommissioned March 25, 1947, she joined the Atlantic Reserve Fleet. She was stricken August 1, 1965 and sold for scrap January 30, 1967. She received three battle stars for her World War II service.
*************
Leonard Roy Harmon, born in Cuero, Texas, on January 21, 1917, enlisted in the U.S. Navy on June 10, 1939, as a Mess Attendant Third Class. He trained at the Naval Training Station, Naval Operating Base, Norfolk, Virginia and reported to [the] San Francisco (CA-38) on October 28, 1939. On November 12, 1942, [the] San Francisco was covering a force of transports disembarking reinforcements off Guadalcanal when Japanese land attack planes, carrying torpedoes, attacked. [The] enemy aircraft crashed into the ship causing “considerable damage and intense fires” that put the after anti-aircraft director and radar out of commission. One officer and 15 men were either killed outright or died of their injuries. Harmon rushed in to evacuate the wounded. He was then assigned to assist Pharmacist’s Mate Lynford Bondsteel in evacuating and caring for the wounded. While the ship was being raked by enemy gunfire, Harmon deliberately shielded Bondsteel in order to protect his wounded shipmate. Although Bondsteel managed to get his courageous shipmate below, Harmon died of his wounds soon afterward.

Citation Excerpt:
The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Mess Attendant First Class Leonard Roy Harmon (NSN: 3600418), United States Navy, for extraordinary heroism and devotion to duty in action against the enemy while serving on board the Heavy Cruiser U.S.S. San Francisco (CA-38) […]. With persistent disregard of his own personal safety, […] Harmon rendered invaluable assistance in caring for the wounded and assisting them to a dressing station. In addition to displaying unusual loyalty [on] behalf of the injured Executive Officer, he deliberately exposed himself to hostile gunfire in order to protect a shipmate and, as a result of this courageous deed, was killed in action. He gallantly gave his life for his country.
