The Navy Unit Commendation may be awarded by the Secretary of the Navy to any unit of the Navy or Marine Corps that distinguishes itself by outstanding heroism in action against an enemy (but not sufficiently to justify the award of the Presidential Unit Citation). It may also be awarded to a unit that distinguishes itself by extremely meritorious service not involving combat (but in support of military operations), which renders that unit outstanding when compared to other units performing similar service.

Description The Battle of Okinawa, codenamed Operation Iceberg. was fought on the Ryukyu Islands of Okinawa and was the largest amphibious assault in the Pacific War of World War II. The 82-day-long battle lastedThe Battle of Okinawa, codenamed Operation Iceberg. was fought on the Ryukyu Islands of Okinawa and was the largest amphibious assault in the Pacific War of World War II. The 82-day-long battle lasted from early April until mid-June 1945. After a long campaign of island hopping, the Allies were approaching Japan, and planned to use Okinawa, a large island only 340 mi (550 km) away from mainland Japan, as a base for air operations on the planned invasion of Japanese mainland (coded Operation Downfall). Four divisions of the U.S. 10th Army (the 7th, 27th, 77th, and 96th) and two Marine Divisions (the 1st and 6th) fought on the island. Their invasion was supported by naval, amphibious, and tactical air forces.
The battle has been referred to as the "typhoon of steel" in English, and tetsu no ame ("rain of steel") or ("violent wind of steel") in Japanese. The nicknames refer to the ferocity of the fighting, the intensity of kamikaze attacks from the Japanese defenders, and to the sheer numbers of Allied ships and armored vehicles that assaulted the island. The battle resulted in the highest number of casualties in the Pacific Theater during World War II. Based on Okinawan government sources, mainland Japan lost 77,166 soldiers, who were either killed or committed suicide, and the Allies suffered 14,009 deaths (with an estimated total of more than 65,000 casualties of all kinds). Simultaneously, 42,000–150,000 local civilians were killed or committed suicide, a significant proportion of the local population. The atomic bombings of Hiroshima and Nagasaki together with the Soviet invasion of Manchuria caused Japan to surrender less than two months after the end of the fighting on Okinawa.... More

By the end of July 1945, the Imperial Japanese Navy was incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on July 26, 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders (the Supreme Council for the Direction of the War, also known as the "Big Six") were privately making entreaties to the still-neutral Soviet Union to mediate peace on terms more favorable to the Japanese. Meanwhile, the Soviets were preparing to attack Japanese forces in Manchuria and Korea (in addition to southern Sakhalin and the Kuril Islands) in fulfillment of promises they had secretly made to the United States and the United Kingdom at the Tehran and Yalta Conferences.

It took place in spring of 1944 and was part of the New Guinea campaThe Battle of Hollandia (code-named Operation Reckless) was an engagement between American and Japanese forces during World war II. It took place in spring of 1944 and was part of the New Guinea campaign. The landings were undertaken simultaneously with the amphibious landings at Aitape ("Operation Persecution") to the east. The battle was an unqualified success for the US forces, resulting in a withdrawal by the Japanese to a new strategic defence line in the west of New Guinea and the abandonment of all positions in the east of the island.
Initial operations commenced in the second week of March 1944 with air raids by the Fast Carrier Force on Palau and islands in the Carolines, while aircraft of the US 5th Air Force and the RAAF attacked Japanese airfields along the New Guinea coast from Wewak to the Vogelkop and on Biak Island.
On 30 March and continuing to 3 April these air forces attacked Hollandia itself and the airfields on the Sentani plain. Achieving complete surprise they were able to destroy nearly 100 aircraft on the ground, leaving 6 Air Div unable to resist the planned invasion.
On 16 to 18 April the amphibious forces sailed from their bases at Finschafen and Goodenough Island, taking evasive routes to confuse their intentions until they arrived off Hollandia during the night of 21/22 April. The landings took place at dawn on 22 April after a supporting naval bombardment at each site.
At Tanahmera Bay the two RCT’s from 24 Div. were able to land without opposition, but found the beach to be highly unsuitable. Backed by a swamp just 30 yards from the shoreline, and with just one exit trail unsuitable for vehicles, Tanahmera Bay was quickly written off as a landing site; while the infantry already ashore pressed on to the Sentani plain the remainder of 24 Div was diverted to Humboldt Bay, which had by this time been secured. After four days under these conditions the two units had reached the western airfield and on 26 April it was secured.
Meanwhile at Humboldt Bay 41 Div. also achieved complete surprise, and though the beaches were defended after the naval bombardment the Japanese troops there uncharacteristically abandoned their positions and fled inland. There was some opposition as they pressed forward, but by 24 April they had reached the lake and by 26 April secured the two eastern airfields. The two forces linked up the same day.
The collapse of Japanese resistance has been attributed to lack of preparedness, due to changes in the command structure and to a lack of combat troops; many of the 11,000 men based there were administrative and support units. None of the senior officers present had been in post more than a few weeks and the senior air officer had been relieved following the destruction of his air forces at the beginning of April. Neither Kitazono nor Endo had been able to prepare a comprehensive defence plan, and in any event had neither the men nor the resources to carry it out. On the other hand the Allied operation had been over-insured; concerns over the strength of the Japanese garrison had left the Allies with a four to one advantage in the event.... More

It took place The Battle of the Philippine Sea (June 19–20, 1944) was a major naval battle of World War II that eliminated the Imperial Japanese Navy's ability to conduct large-scale carrier actions. It took place during the United States' amphibious invasion of the Mariana Islands during the Pacific War. The battle was the last of five major "carrier-versus-carrier" engagements between American and Japanese naval forces, and pitted elements of the United States Navy's Fifth Fleet against ships and aircraft of the Imperial Japanese Navy's Mobile Fleet and nearby island garrisons.
The aerial part of the battle was nicknamed the Great Marianas Turkey Shoot by American aviators for the severely disproportional loss ratio inflicted upon Japanese aircraft by American pilots and anti-aircraft gunners. During a debriefing after the first two air battles a pilot from USS Lexington remarked "Why, hell, it was just like an old-time turkey shoot down home!" The outcome is generally attributed to American improvements in pilot and crew training and tactics, technology (including the top-secret anti-aircraft proximity fuze), and ship and aircraft design. Although at the time the battle appeared to be a missed opportunity to destroy the Japanese fleet, the Imperial Japanese Navy had lost the bulk of its carrier air strength and would never recover. During the course of the battle, American submarines torpedoed and sank two of the largest Japanese fleet carriers taking part in the battle.
This was the largest carrier-to-carrier battle in history.... More

The Allied invasion fleet embarking the expedThe Battle of Saipan was a battle of the Pacific campaign of World War II, fought on the island of Saipan in the Mariana Islands from 15 June–9 July 1944. The Allied invasion fleet embarking the expeditionary forces left Pearl Harbor on 5 June 1944, the day before Operation Overlord in Europe was launched. The U.S. 2nd Marine Division, 4th Marine Division, and 27th Infantry Division, commanded by Lieutenant General Holland Smith, defeated the 43rd Division of the Imperial Japanese Army, commanded by Lieutenant General Yoshitsugu Saito.
Bombardment of Saipan began on 13 June 1944. Fifteen battleships were involved, and 165,000 shells were fired. Seven modern fast battleships delivered twenty-four hundred 16 in (410 mm) shells, but to avoid potential minefields, fire was from a distance of 10,000 yd (9,100 m) or more, and crews were inexperienced in shore bombardment. The following day the eight older battleships and 11 cruisers under Admiral Jesse B. Oldendorf replaced the fast battleships but were lacking in time and ammunition.
The landings[4] began at 07:00 on 15 June 1944. More than 300 LVTs landed 8,000 Marines on the west coast of Saipan by about 09:00. Eleven fire support ships covered the Marine landings. The naval force consisted of the battleships Tennessee and California. The cruisers were Birmingham and Indianapolis. The destroyers were Norman Scott, Monssen, Colahan, Halsey Powell, Bailey, Robinson and Albert W. Grant. Careful Japanese artillery preparation — placing flags in the lagoon to indicate the range — allowed them to destroy about 20 amphibious tanks, and the Japanese strategically placed barbed wire, artillery, machine gun emplacements, and trenches to maximize the American casualties. However, by nightfall the 2nd and 4th Marine Divisions had a beachhead about 6 mi (10 km) wide and 0.5 mi (1 km) deep. The Japanese counter-attacked at night but were repulsed with heavy losses. On 16 June, units of the U.S. Army's 27th Infantry Division landed and advanced on the airfield at Ås Lito (which is now the location of Saipan International Airport). Again the Japanese counter-attacked at night. On 18 June, Saito abandoned the airfield.
The invasion surprised the Japanese high command, which had been expecting an attack further south. Admiral Soemu Toyoda, commander-in-chief of the Japanese Navy, saw an opportunity to use the A-Go force to attack the U.S. Navy forces around Saipan. On 15 June, he gave the order to attack. But the resulting battle of the Philippine Sea was a disaster for the Imperial Japanese Navy, which lost three aircraft carriers and hundreds of planes. The garrisons of the Marianas would have no hope of resupply or reinforcement.
Without resupply, the battle on Saipan was hopeless for the defenders, but the Japanese were determined to fight to the last man. Saito organized his troops into a line anchored on Mount Tapotchau in the defensible mountainous terrain of central Saipan. The nicknames given by the Americans to the features of the battle — "Hell's Pocket", "Purple Heart Ridge" and "Death Valley" — indicate the severity of the fighting. The Japanese used the many caves in the volcanic landscape to delay the attackers, by hiding during the day and making sorties at night. The Americans gradually developed tactics for clearing the caves by using flamethrower teams supported by artillery and machine guns.
The operation was marred by inter-service controversy when Marine General Holland Smith, unsatisfied with the performance of the 27th Division, relieved its commander, Army Major General Ralph C. Smith. However, General Holland Smith had not inspected the terrain over which the 27th was to advance. Essentially, it was a valley surrounded by hills and cliffs under Japanese control. The 27th took heavy casualties and eventually, under a plan developed by General Ralph Smith and implemented after his relief, had one battalion hold the area while two other battalions successfully flanked the Japanese.
By 7 July, the Japanese had nowhere to retreat. Saito made plans for a final suicidal banzai charge. On the fate of the remaining civilians on the island, Saito said, "There is no longer any distinction between civilians and troops. It would be better for them to join in the attack with bamboo spears than be captured." At dawn, with a group of 12 men carrying a great red flag in the lead, the remaining able-bodied troops — about 3,000 men — charged forward in the final attack. Amazingly, behind them came the wounded, with bandaged heads, crutches, and barely armed. The Japanese surged over the American front lines, engaging both army and Marine units. The 1st and 2nd Battalions of the 105th Infantry Regiment were almost destroyed, losing 650 killed and wounded. However, the fierce resistance of these two battalions, as well as that of Headquarters Company, 105th Infantry, and supply elements of 3rd Battalion, 10th Marine Artillery Regiment resulted in over 4,300 Japanese killed. For their actions during the 15-hour Japanese attack, three men of the 105th Infantry were awarded the Medal of Honor — all posthumously. Numerous others fought the Japanese until they were overwhelmed by the largest Japanese Banzai attack in the Pacific War.
By 16:15 on 9 July, Admiral Turner announced that Saipan was officially secured. Saito — along with commanders Hirakushi and Igeta — committed suicide in a cave. Also committing suicide at the end of the battle was Vice-Admiral Chuichi Nagumo — the naval commander who led the Japanese carriers at Pearl Harbor and Midway — who had been assigned to Saipan to direct the Japanese naval air forces based there.
In the end, almost the entire garrison of troops on the island — at least 30,000 — died. For the Americans, the victory was the most costly to date in the Pacific War. 2,949 Americans were killed and 10,464 wounded, out of 71,000 who landed. Hollywood actor Lee Marvin was among the many American wounded. He was serving with "I" Company, 24th Marine Regiment, when he was shot in the buttocks by Japanese machine gun fire during the assault on Mount Tapochau. He was awarded the Purple Heart and was given a medical discharge with the rank of Private First Class in 1945.... More
Description The Battle of Leyte Gulf, also called the Battles for Leyte Gulf, and formerly known as the Second Battle of the Philippine Sea, is generally considered to be the largest naval battle of World War II The Battle of Leyte Gulf, also called the Battles for Leyte Gulf, and formerly known as the Second Battle of the Philippine Sea, is generally considered to be the largest naval battle of World War II and, by some criteria, possibly the largest naval battle in history.
It was fought in waters near the Philippine islands of Leyte, Samar and Luzon from 23–26 October 1944, between combined US and Australian forces and the Imperial Japanese Navy. On 20 October, United States troops invaded the island of Leyte as part of a strategy aimed at isolating Japan from the countries it had occupied in Southeast Asia, and in particular depriving its forces and industry of vital oil supplies. The Imperial Japanese Navy (IJN) mobilized nearly all of its remaining major naval vessels in an attempt to defeat the Allied invasion, but was repulsed by the US Navy's 3rd and 7th Fleets. The IJN failed to achieve its objective, suffered very heavy losses, and never afterwards sailed to battle in comparable force. The majority of its surviving heavy ships, deprived of fuel, remained in their bases for the rest of the Pacific War.
The Battle of Leyte Gulf consisted of four separate engagements between the opposing forces: the Battle of the Sibuyan Sea, the Battle of Surigao Strait, the Battle of Cape Engaño and the Battle off Samar, as well as other actions.
It was the first battle in which Japanese aircraft carried out organized kamikaze attacks. By the time of the battle, Japan had fewer aircraft than the Allied forces had sea vessels, demonstrating the difference in power of the two sides at this point of the war. ... More

The campaign began with Japanese landings and occupation of several areas in the British Solomon Islands and Bougainville, in the Territory of New Guinea, during the first six months of 1942. The Japanese occupied these locations and began the construction of several naval and air bases with the goals of protecting the flank of the Japanese offensive in New Guinea, establishing a security barrier for the major Japanese base at Rabaul on New Britain, and providing bases for interdicting supply lines between the Allied powers of the United States and Australia and New Zealand.
The Allies, in order to defend their communication and supply lines in the South Pacific, supported a counteroffensive in New Guinea, isolated the Japanese base at Rabaul, and counterattacked the Japanese in the Solomons with landings on Guadalcanal (see Guadalcanal Campaign) and small neighboring islands on 7 August 1942. These landings initiated a series of combined-arms battles between the two adversaries, beginning with the Guadalcanal landing and continuing with several battles in the central and northern Solomons, on and around New Georgia Island, and Bougainville Island.
In a campaign of attrition fought on land, on sea, and in the air, the Allies wore the Japanese down, inflicting irreplaceable losses on Japanese military assets. The Allies retook some of the Solomon Islands (although resistance continued until the end of the war), and they also isolated and neutralized some Japanese positions, which were then bypassed. The Solomon Islands campaign then converged with the New Guinea campaign.... More

Two independent, coordinate commands, one in the Southwest Pacific under General of the Army Douglas MacArthur and the other in the Central, South, and North Pacific (Pacific Ocean Areas) under Fleet Admiral Chester W. Nimitz, were created early in the war. Except in the South and Southwest Pacific, each conducted its own operations with its own ground, air, and naval forces in widely separated areas. These operations required at first only a relatively small number of troops whose efforts often yielded strategic gains which cannot be measured by the size of the forces involved. Indeed, the nature of the objectivesùsmall islands, coral atolls, and jungle-bound harbors and airstrips, made the employment of large ground forces impossible and highlighted the importance of air and naval operations. Thus, until 1945, the war in the Pacific progressed by a double series of amphibious operations each of which fitted into a strategic pattern developed in Washington.... More

Description In the Pacific Theater of World War II, the Gilbert and Marshall Islands campaign, from November 1943 through February 1944, were key strategic operations of the United States Pacific Fleet and MarineIn the Pacific Theater of World War II, the Gilbert and Marshall Islands campaign, from November 1943 through February 1944, were key strategic operations of the United States Pacific Fleet and Marine Corps in the Central Pacific. The purpose was to establish airfields that would allow land based air support for the upcoming operations across the Central Pacific. The campaign began with a costly three-day battle for the island of Betio at the Tarawa atoll. The campaign was preceded a year earlier by a diversionary raid on Makin Island by U.S. Marines in August, 1942.
About 4,000 kilometers southwest of the Hawaii Islands, the Marshall Islands represented part of the perimeter of the Japanese Pacific empire. The former German colony was given to Japan after the closure of WW1, and had since been an important part of both offensive and defensive plans of the Japanese Navy. By the end of 1943, Admiral Mineichi Koga of the Japanese Combined Fleet knew the Americans were eyeing the islands, but he could not figure out where they would strike. His difficulties were further complicated by the lack of carrier aircraft, as they were taken away from him in an attempt to reinforce land-based squadrons. With his hands tied, all Koga could do was to send his submarines out as forward observers and order the regional commander in Truk Admiral Masashi Kobayashi to reinforce the island garrisons that were most exposed to American attacks. Kobayashi shifted men to the outer islands of Jaluit, Mili, Wotje, and Maloelap. In total, Kobayashi had 28,000 troops available to him in the Marshall Islands. For a garrison that size ground fortifications were sub-par, but that was rather by design at this stage of the war, for that Tokyo had since decided that the Marshall Islands were to serve only as a part of a delay action campaign. The new defensive perimeter was to be established much closer to the home islands.
American intelligence decoded Japanese messages and detected movements for the outer islands, and decided to change the invasion plans. Unbeknownst to the Japanese, the Americans were now bypassing the reinforced outer islands; they were now directly attacking Kwajalein and Eniwetok.... More
Description Operation Hailstone was a massive naval air and surface attack launched on February 16–17, 1944, during World War II by the United States Navy against the Japanese naval and air base at Truk in the CaOperation Hailstone was a massive naval air and surface attack launched on February 16–17, 1944, during World War II by the United States Navy against the Japanese naval and air base at Truk in the Caroline Islands, a pre-war Japanese territory.
The U.S. attack involved a combination of airstrikes, surface ship actions, and submarine attacks over two days and appeared to take the Japanese completely by surprise. Several daylight, along with nighttime, airstrikes employed fighters, dive bombers, and torpedo aircraft in attacks on Japanese airfields, aircraft, shore installations, and ships in and around the Truk anchorage. A force of U.S. surface ships and submarines guarded possible exit routes from the island's anchorage to attack any Japanese ships that tried to escape from the airstrikes.
In total the attack sank three Japanese light cruisers (Agano, Katori, and Naka), four destroyers (Oite, Fumizuki, Maikaze, and Tachikaze), three auxiliary cruisers (Akagi Maru, Aikoku Maru, Kiyosumi Maru), two submarine tenders (Heian Maru, Rio de Janeiro Maru), three other smaller warships (including submarine chasers CH-24 and Shonan Maru 15), aircraft transport Fujikawa Maru, and 32 merchant ships. Some of the ships were destroyed in the anchorage and some in the area surrounding Truk lagoon. Many of the merchant ships were loaded with reinforcements and supplies for Japanese garrisons in the central Pacific area. Very few of the troops aboard the sunken ships survived and little of their cargoes were recovered.
Maikaze, along with several support ships, was sunk by U.S. surface ships while trying to escape from the Truk anchorage. On 17 February 1944, while evacuating convoys to Yokosuka from Truk following Allied attack on Truk, Maikaze, the cruiser Katori, and the auxiliary cruiser Akagi Maru were sunk by gunfire from the cruisers Minneapolis, New Orleans, and the battleship New Jersey 40 miles (64 km) northwest of Truk. Maikaze herself was sunk with all hands on board. The survivors of the sunken Japanese ships reportedly refused rescue efforts by the U.S. ships.
The cruiser Agano, a veteran of the Raid on Rabaul and which was already en route to Japan when the attack began, was sunk by a U.S. submarine, Skate. Oite rescued 523 survivors from Agano and returned to Truk lagoon to assist in its defense with her anti-aircraft guns. She was sunk soon after by air attack with the Agano survivors still on board, killing all of them and all but 20 of Oite's crew.
Over 250 Japanese aircraft were destroyed, mostly on the ground. Many of the aircraft were in various states of assembly, having just arrived from Japan in disassembled form aboard cargo ships. Very few of the assembled aircraft were able to take off in response to the U.S. attack. Several Japanese aircraft that did take off were claimed destroyed by U.S. fighters or gunners on the U.S. bombers and torpedo planes.
The U.S. lost twenty-five aircraft, mainly due to the intense anti-aircraft fire from Truk's defenses. About 16 U.S. aircrew were rescued by submarine or amphibious aircraft (several Japanese, whose crew took them prisoner). A nighttime torpedo attack by a Japanese aircraft from either Rabaul or Saipan damaged Intrepid and killed 11 of her crew, forcing her to return to Pearl Harbor and later, San Francisco for repairs. She returned to duty in June, 1944. Another Japanese air attack slightly damaged the battleship Iowa with a bomb hit.
An aerial view of the airstrike at Truk can be seen in the U.S. Navy film The Fighting Lady.
One well-known pilot, U.S. Marine Corps ace Gregory "Pappy" Boyington, survived this raid while being held prisoner on Truk, after being captured at Rabaul.
Aftermath
The attacks for the most part ended Truk as a major threat to Allied operations in the central Pacific; the Japanese garrison on Eniwetok was denied any realistic hope of reinforcement and support during the invasion that began on February 18, 1944, greatly assisting U.S. forces in their conquest of that island.
The Japanese later relocated about 100 of their remaining aircraft from Rabaul to Truk. These aircraft were attacked by U.S. carrier forces in another attack on April 29–30, 1944 which destroyed most of them. The U.S. aircraft dropped 92 bombs over a 29-minute period to destroy the Japanese planes. The April 1944 strikes found no shipping in Truk lagoon and were the last major attacks on Truk during the war.
Truk was isolated by Allied (primarily U.S.) forces as they continued their advance towards Japan by invading other Pacific islands such as Guam, Saipan, Palau, and Iwo Jima. Cut off, the Japanese forces on Truk, like on other central Pacific islands, ran low on food and faced starvation before Japan surrendered in August 1945.... More
