Fourth period: January 1942-September 1942
This period was characterized by heavy sinking on the coast of United States. Japanese ships sank and the country incurred heavy losses. The submarine was responsible for those shipping losses. Major changes were made in the war whereby the battleships were no longer used. This was a result of the attack that happened in Japan in 1941. The U.S entry into the war led to the rapid expansion of the scope of U-boat operations. Additionally, America integrated submarines in her military operations. The submarine was characterized by unique designs and powerful machines. Since German had a large and rapidly increasing U-boat fleet, they were able to launch a full-scale attack against the feebly protected

Navy sent out all available planes and blimps to battle the U-boats along the coast. They were aided by the First Bomber Command, initial Army Air Forces contribution, which was activated in December 1941. During this period, several scientific and technical advances were achieved to aid the antisubmarine war. Germans were fully alive to possibilities of meter-wave radar, and they were aided by the capture of Mark II radar set in Tunisia in the spring of 1942. Admiral Doenitz demanded quick equipping of all U-boats with the makeshift equipment. Another new device introduced by the U-boats was Submarine Bubble Target (SBT) or “Pillenwerfer” which were to be released by the U-boats when attacked by surface craft. The dissolving tablets formed bubbles that produced false sonar targets which were envisioned to throw the attacking ships off the track of the U-boat (Hackmann, 1984). In early1942, a new type of passive defense against the torpedo attacks, known as Admiralty Net Defense (AND), was being fitted to merchant ships which reduced the probabilities of the ships being torpedoed by the U-boat by 50%. In March 1942, the Hedgehog charges were made more deadly by filling them with Torpex. Magnetic Airborne Detector (MAD) was also developed during this phase to facilitate aircraft trail submerged submarines (Hackmann, …show more content…
By October, the U-boats were returning to the North Atlantic in force with attacks on transatlantic convoys being their aims and operated in the mid-ocean gap that could not be accessed by land-based air patrols (Gardner, 1996). This gave them the liberty to operate on the surface and gathered very large wolf packs, therefore, leading to the breaks in the escort formation and disorganization of the defense. In the spring of 1943, the convoy defenses were reinforced by a few aircraft patrol in the mid-ocean gap, which attested to be unexpectedly effective. A good number of U-boats were sunk, but they continued to attack until May when they were sent off from ONS 5 in the pivotal convoy battle of the war (Hackmann,
On August 2nd 1964, two United States Navy ships were secretly attacked by the North Vietnamese torpedo boats in the Gulf of Tonkin. A few days later, another two U.S. Destroyer boats were attacked by North Vietnamese torpedo
This is what the authors of this article would have you believe. On 23 February 1942, a Japanese submarine shelled Santa Barbara, California; later were reports of submarines shelling points in Oregon (Granatstein and Johnson, 118). In early June, Japan launched an attack on the Aleutian Islands. The intent was to draw out American fleet, destroy it, and prepare for an attack on the continental North America. Ultimately the plan failed, along with Japanese imperial ambitions, after the American victory at the Battle of Midway.
Japanese bombers Attacked the U.S Navy’s Pacific Fleet at the Pearl Harbor on December 7, 1941. The U.S Navy also had problems with communication because of the Japanese Code Breakers were faster at breaking codes than the Americans making a new code. Many of the Japanese were learning English in the U.S. They had also learned lots of the slang terms. The battle
The battle demonstrated the importance of using carriers and aircraft in coordinated attacks, as well as the value of accurate and timely intelligence. These lessons influenced the naval strategies moving forward after the
The Battle of Midway was fought almost entirely with aircrafts. The battle began on June 3, 1942, when U.S. bombers from Midway Island struck at the Japanese invasion force about 220 miles southwest of the U.S. fleet. The U.S. planes quickly sank three of the heavy Japanese carriers and one heavy cruiser. Analysts often point to Japanese aircraft losses at Midway as eliminating the power of the Imperial Navy’s air arm, but in fact about two-thirds of air crews survived. The Battle of Midway brought the Pacific naval forces of Japan and the United States to approximate parity and marked a turning point of the military struggle between the two
In late spring of 1942, the United States and Japan engaged in a series of naval battles, climaxing in the Battle of Midway on June 3–6, 1942, in which Japan suffered a catastrophic defeat. For the next year, the United States engaged Japan in a protracted struggle for the Solomon Islands, which lay near vital Allied shipping routes. Between August 1942 and February 1943, Allied forces carried out an invasion on the island of Guadalcanal—the beginning of a long series of Allied offensives that would eventually force the
Once the United States started pushing forward, the Japanese opened
On December 7th, 1941, the United states was attacked by the Japanese in the United States naval base at Pearl Harbor near Honolulu, Hawaii. The day after this devastating event, the Unites States congress and President Franklin D. Roosevelt, declared war against Japan. As Germany and Italy had allied with Japan, they also declared war on America. Two years later, the United States found themselves joining World War II. America had soon launched a way to get back at Japan for invasion of Pearl Harbor.
Rahul Bagga Mr.Campbell US History, Period 0 16 December 2015 Why did Japan attack Pearl Harbor? One day that will always be remembered by America is the date of December 7, 1941, which changed American history forever. December 7, 1941 was the day the Japanese warplanes attacked Pearl Harbor (Hawaii) which stationed many of American ships and airfields. Immediately after the bombings, United States President Franklin Roosevelt declared war on Japan, leading to a direct involvement into World War ll. Japan had many reason to do so but Japan attacked Pearl harbor for three reasons which were that they had a plan for a new world order, United States were expanding their number of naval ships rapidly, and an oil embargo was placed upon Japan
The Air War at Sea, Stackpole Books: Mechanicsburg, PA, 2005). The objective was for a landing force to sail with troop filled transports, supporting war ships and the light carrier, Shoho. The main Japanese objective in the Solomons was the capture of Tulagi, the colonial capital. “To protect these two invasion fleets, Zuikaku and Shokaku would lead a separate covering force to create a blanket of air protection” (Bennett, Geoffrey, Naval Battles of World War Two, Pen & Sword: Barnsley, UK, 1975, 2003). U.S. intelligence relied heavily on the use of direction-finding equipment to learn where Japanese ships were and where they were heading.
Political leadership, military strategy, organizational capacity, fighting skills and effectiveness, technology, mass production, resources, ideology, and morale, all were essential factors that influenced the war victory. The war at sea saw mainly the US and Japan competing in the Pacific and the US and Great Britain competing against Germany in the Atlantic. The offensiveness of the Japanese Empire could be contained and defeated by the US only after the fortunate victory of Midway in 1942 and the following buildup of an overwhelming superiority of the American forces. In the Atlantic, the German U-boats inflicted embarrassing losses to the British and American Navies. Only technological improvements and effective adaptation of the tactics (naval convoy tactics and dedicated anti-submarine airplane) allowed the Allies to recover the situation, regaining control of the sea.
Their scout planes eventually located the US aircraft carriers, but the Japanese were not in a position to target them, based on how dispersed the Japanese naval groups were. If more scout planes were moved to the Carrier Group from the Battle Group, they would have had a more effective coverage area. They would have been in a position to identify the actual size of the US Fleet involved in the defense of Midway and been able to realize that the ships that the Japanese scouts were reporting were actually a threat and they needed to be targeted in a higher priority than Midway. Yamamoto sending scouts from the Battle Group to the Carrier Group could have accomplished this. Scouts were initially sent out on the early in the morning of 4 Jun 1942, if the Japanese had sent the scouts out a few days earlier, they would have been able to identify the disposition of US Naval assets.
Unrestricted submarine warfare outraged many Americans because its application was an attack upon innocent civilian. Unrestricted submarine warfare also breaks an international law which states that the civilians of two warring countries are not targets. Germany not only harmed civilians, but it also broke international law. Through the sinking of the Lusitania, the public’s view of Germany’s unrestricted warfare policy intensified, and more people began to favor American involvement in the war. The sinking of the Lusitania became one of the most important events of the Great War because its reaction is, “the first step towards American involvement in the war.”
As Germany returns, in 1917, to the policy of unrestricted submarine warfare, it came back to renew its suspension in response from force of the United States and other neutral countries. Unrestricted submarine warfare was first initiated in World War I on February 4th, 1915. Germany declared the area around the British Isles a war zone, in which all merchant ships, would be attacked by the German navy. On April 22nd, 1915, the German Embassy published a warning in newspapers to tell passengers that travel on Allied ships are “at their own risk.” One ship, called The Lusitania, was the first to submerge and depart, killing nearly 1300 passengers.
Japan’s attack on Pearl Harbor is by far one of America’s most remembered events in history. On December 7, 1941, the Japanese dropped bombs on the American base at Pearl Harbor, Hawaii. This attack is what persuaded President Franklin Roosevelt to join World War 2 and fight on two fronts. Japan attacked Pearl Harbor for many reasons. They attacked because they believed they would create a New World Order, they felt threatened by America and because of the oil embargo.
