The Northrop Grumman X-47B failed to land on the USS George H.W. Bush (CVN-77) on Monday in the Navy’s fourth and final attempt to land the unmanned autonomous vehicle, according to a late Tuesday statement from Naval Air Systems Command.
“Aircraft ‘Salty Dog 501’ was launched to the ship on July 15 to collect additional shipboard landing data. During the flight, the aircraft experienced a minor test instrumentation issue and returned to Naval Air Station Patuxent River, where it safely landed,” Naval Air Systems Command said in a statement to press.

Forget Moby Dick’s white whale – a tropical cyclone is by far the most difficult ocean beast to track. This rotating system of clouds and thunderstorms, most commonly known to North Americans as a hurricane once it reaches a certain size and speed, is typically several hundred miles wide with winds as fast as 155 miles per hour.
These vast storms are essentially a physics puzzle, in which the interaction of moisture, wind, air, heat and other elements can trick even the most knowledgeable scientists trying to forecast both the path and intensity of a hurricane. In the last decade, weather models have gotten much better at predicting path and landfall, but they have been less skillful when trying to estimate pressure and maximum wind speeds. Read More →

The following is from the executive summary of the June 24, 2013 U.S. Coast Guard Report: Report of Investigation into the Fire Onboard the CARNIVAL SPLENDOR which occurred in the Pacific Ocean off the Coast of Mexico on November 8, 2010, which Resulted in Complete Loss of Power.
On November 8, 2010 at 0600 (Local Time), the Carnival Splendor was underway off the coast of Mexico when the vessel suffered a major mechanical failure in the number five diesel generator. As a result, engine components, lube oil and fuel were ejected through the engine casing and caused a fire at the deck plate level between generators five and six in the aft engine room which eventually ignited the cable runs overhead. The fire in the cable runs was relatively small, but produced a significant volume of smoke which hampered efforts to locate and extinguish it. In addition, the fire caused extensive damage to the cables in the aft engine room, which contributed to the loss of power. Read More →
Eugene Parks Wilkinson was born in Long Beach, California, on 10 August 1918, the son of Dennis William and Daisy Parks Wilkinson. He attended Holtville, California, High School and San Diego State College. He graduated from the latter in 1938 with a Bachelor of Arts degree with a major in chemistry. He taught chemistry there for a year. He also filled in and taught a course in mathematics. During this year he attended the University of Southern California. The next year he had a teaching fellowship in chemistry at USC. During those two years he completed all of the course work for a doctor’s degree but never did a thesis or received any graduate degree. Commissioned ensign in the U.S. Naval Reserve on 12 December 1940, he was transferred to the regular U.S. Navy on 28 August 1946. Read More →

The commandant of the Marine Corps and the chief of naval operations made the case for forward presence in an era of declining defense spending at a Washington to a national security forum think tank last week as events in Egypt threaten to spiral out of control.
Adm. Jonathan Greenert explained how the Navy and the Marine Corps can react quickly to situations citing the movement of USS Kearsarge (LHD-3) and USS San Antonio (LPD-17) into the Red Sea following the Egyptian military’s removal of President Mohamed Morsi from office as an immediate example of forward presence’s value and tailored forces. The ships were sent closer to the conflict, “because we don’t know what’s going to happen” in Egypt. “We can’t garrison and respond. It will be too late,” to handle a possible evacuation of Americans from the country, Greenert said. Read More →

Seven Oliver Hazard Perry-class frigates are up for Foreign Military Sale (FMS), according to a list of ships the Navy plans to decommission by the end of 2014.
The list, issued on Wednesday, included a Los Angeles-class nuclear attack boat USS Dallas (SSN-700), minesweeper USS Avenger (MCM-1), an amphibious warship and two Military Sealift Command ships. Read More →

The Navy has entered a new age in carrier aviation with the successful landing of the unmanned Northrop Grumman X-47B on the USS George H.W. Bush (CVN-77), the service announced at 1:45 p.m. EST on Wednesday.
Call sign Salty Dog 502 left Naval Air Station Patuxent River, Md. shortly after 12:00 p.m. EST and flew to the Bush controlled through a complex series of algorithms and navigational sensors and landed on the deck of the Nimitz-class aircraft carrier guided not with a joystick and throttle controls but by an operator with a mouse and a keyboard.
