Construction of USS Juneau
USS Juneau was laid down on May 27, 1940, at the Federal Shipbuilding and Drydock Company in Kearny, New Jersey. Launched on October 25, 1941, and sponsored by Mrs. Harry Lucas, the cruiser was commissioned on February 14, 1942, under the command of Captain Lyman K. Swenson. Juneau’s quick entry into service highlighted the urgent wartime need for new ships, setting the stage for her extensive operations across both the Atlantic and Pacific theaters.
Plot Points
Armament Overview
Juneau was armed with a formidable battery designed for multiple combat roles. The Atlanta-Class layout included:
| Component | Details |

Service History of the USS Juneau
Following a quick shakedown cruise along the Atlantic coast in the spring of 1942, Juneau began blockade duties near the islands of Martinique and Guadeloupe. Her mission was to prevent the escape of Vichy French ships. After returning to New York for alterations, she sailed the North Atlantic and Caribbean on escort and patrol duties. On August 22, 1942, she was sent to the Pacific. There, Juneau joined her sister ship, USS Atlanta.
USS Juneau joined Task Force 18 on September 10 under Rear Admiral Leigh Noyes, whose flagship, USS Wasp, was central to ferrying fighter aircraft to Guadalcanal. When Wasp suffered fatal torpedo hits on September 15 from Japanese submarine I-19, Juneau, along with accompanying destroyers, rescued nearly 2,000 survivors and safely delivered them to Espiritu Santo. Soon after, she resumed active operations with Task Force 17, supporting actions including the Buin-Faisi-Tonolai Raid, the Battle of the Santa Cruz Islands, and the monumental Naval Battle of Guadalcanal.
Battle of the Santa Cruz Islands
At the break of dawn on October 26, 1942, US carrier aircraft detected a sizable Japanese formation moving toward Guadalcanal. American pilots quickly launched an aggressive assault, inflicting heavy damage on the enemy by striking two carriers—Zuihō and Shōkaku—along with the heavy cruiser Chikuma and two destroyers. As aircraft engaged the enemy from above, the surface vessels were suddenly caught in a hail of anti-aircraft fire.
Shortly after 10:00 AM, approximately 27 enemy planes swooped in to attack Hornet’s formation. USS Juneau and the other screening ships responded with a fierce anti-aircraft barrage. Their combined shot down nearly 20 enemy aircraft. Despite the valiant effort, Hornet was heavily damaged by the assault and would ultimately sink the following day.
Juneau soon detached from Hornet’s escort to join the Enterprise group, which was enduring its own fierce engagement several miles away. Over the course of the battle, Juneau played a crucial role in repelling four separate Japanese air attacks, contributing to the downing of 18 enemy aircraft through her well-coordinated AA efforts.
By evening, the American forces were forced to retire to the southeast. Despite the high cost in terms of damage and loss, the battle marked a turning point. The combination of the Marine victory on Guadalcanal and the significant damage inflicted on two key Japanese carriers had a profound impact, effectively blunting the enemy’s ability to project air power in the subsequent phases of the Guadalcanal campaign.
Naval Battle of Guadalcanal
On November 8, 1942, Juneau set sail from Nouméa, New Caledonia, as part of Task Force 67 under Rear Admiral Richmond K. Turner. Her mission was to escort reinforcements to Guadalcanal. The fleet reached the island in the early hours of November 12, and Juneau quickly assumed her position in the protective screen encircling the supply vessels. For several hours, the unloading operations proceeded smoothly—until the calm was shattered at 14:05 by the sudden appearance of 30 Japanese aircraft.
The incoming attack was swift and fierce. Amid the chaos, Juneau’s anti-aircraft batteries alone downed six enemy torpedo bombers. Only a single bomber managed to break through the protective screen.
As daylight faded, an American attack group of cruisers and destroyers was dispatched to clear Guadalcanal following reports of a large enemy surface force converging on the island. At 01:48 on November 13, under the command of Rear Admiral Daniel J. Callaghan, a relatively small landing support group—of which Juneau was a part—moved to engage this enemy formation. The Japanese contingent comprised of two battleships, one light cruiser, and nine destroyers, setting the stage for one of the most intense naval engagements of the campaign.
The Sinking of USS Juneau
The ensuing melee was marked by chaos and confusion. With bad weather and disrupted communications in a battlefield set in near-pitch darkness, the opposing fleets became engaged at almost point-blank range. In the heart of the clash, USS Juneau was struck on her port side by a torpedo launched from the Japanese destroyer Amatsukaze, inflicting severe damage and causing the cruiser to list dramatically. Despite her efforts to maintain formation, she was forced to withdrawal.
Before noon on November 13, Juneau, along with the damaged cruisers Helena and San Francisco, started toward Espiritu Santo for emergency repairs. At this point, Juneau was struggling—propelled by only one functioning screw—keeping station approximately 800 yards off the starboard quarter of the equally battered San Francisco. With her bow down by 12 feet, she managed to sustain a speed of 13 knots.
Minutes after 11:00 AM, Japanese submarine I-26 launched two torpedoes. Aimed at San Francisco, both narrowly missed their intended target;but one found Juneau, hitting her in the same area struck earlier. A cataclysmic explosion split the cruiser in two, and she vanished beneath the waves, all in a mere 20 seconds. Fearing additional submarine attacks, and believing that no one survived the explpsion, both Helena and San Francisco continued, without initiating rescue efforts.
It is believed that over 100 sailors initially survived Juneau’s sinking. Adrift in the open ocean, they were subjected to the elements and relentless shark attacks for eight days. When rescue finally arrived, only 10 survivors remained.
Only on November 20, 1942, USS Ballard recovered two survivors, a PBY seaplane rescued five more from a raft, and three additional sailors—one critically wounded—managed to reach San Cristobal Island, nearly 55 miles away from the site of the sinking.
Among the casualties were the five Sullivan brothers—symbols of family sacrifice whose memory continues to evoke respect. Some accounts suggest that two of the Sullivan brothers initially survived the sinking only to later succumb in the water. One survivor recalled that he had remained with one of the Sullivan brothers for several agonizing days.
