This I found interesting, the Navy is going to be installing a new type of catapult system on it's newest aircraft carrier class, the Ford Class carriers.

It will allow the launching of both heaver and lighter aircraft, including the small drones that can not be launched by catapults now, because the current steam powered catapults can not be tuned down that low. It uses the same technology in the recovery of aircraft, which will also allow lighter (drones) to be recovered, which can not be done now with the hydraulic recovery system.




The United States Navy made history on Dec. 18 when it launched the first aircraft using the Electromagnetic Aircraft Launch System (EMALS).

This technology will replace the steam catapult system relied on for more than 50 years to launch aircraft from carriers. Newer, heavier and faster aircraft will result in launch energy requirements approaching the steam system's limits.

EMALS is a complete carrier-based launch system designed for all future Ford-class, nuclear-powered carriers that are replacing the Nimitz-class carrier in use since 1975. The first ship of this new class, the Gerald R. Ford, is currently under construction and slated for completion in 2015.

The Aircraft Launch and Recovery Equipment (ALRE) program launched an F/A-18E Super Hornet Dec. 18 from a New Jersey test site using the EMALS technology.

"This is a tremendous achievement not just for the ALRE team, but for the entire Navy," said Capt. James Donnelly, ALRE program manager. "Saturday's EMALS launch demonstrates an evolution in carrier flight deck operations using advanced computer control, system monitoring and automation for tomorrow's carrier air wings."

"I thought the launch went great," said Lt. Daniel Radocaj, the test pilot who made the first EMALS manned launch. "I got excited once I was on the catapult, but I went through the same procedures as on a steam catapult. The catapult stroke felt similar to a steam catapult and EMALS met all of the expectations I had."

The mission and function of EMALS remains the same as the steam catapult; however, EMALS employs entirely different technologies. EMALS will deliver the necessary higher launch energy capacity as well as substantial improvements in system weight, maintenance, increased efficiency and more accurate end-speed control.

The system's technology allows for a smooth acceleration at both high and low speeds, increasing the carrier's ability to launch aircraft in support of the warfighter. EMALS will provide the capability for launching all current and future carrier air wing platforms — lightweight unmanned to heavy strike fighters.

Engineers will continue system functional demonstration testing on EMALS and will expand aircraft launches next year.

Good one Baldy , It looks very similar to the " Steam launch " The experiment was conducted at Ground level with no reference to actual lets say " Deck length " But was cool anyway .

I've read several articles about this, the length of take off was about 300 ft. Which is about the same as for a steam catapult.

So all in all the simplicity of the Electromagnetic system and the reduced space under deck is quite beneficial over all . You have to love new technology .

Yes, plus the many other advantages. The steam catapults were very hard to maintain and use and slow to rebuild the pressure for the next launch. With this new system, they can launch as fast as they can hook them up. It also uses less people in the system. It can launch much heavier and much lighter planes that can be done now by steam.

Of course, this is only one of the new systems being put into place on the Gerald R. Ford (CVN 78). For more information:

When were you in and what aircraft carrier?

I've never been in. When I was that age, the Vietnam war was still going on, but starting to wind down. I turned 18 the year that the draft lottery started. My number was in the high 200's, so I wasn't called. Plus, I had gotten married and had a child by the time I was 18. At that time, my impression of the military wasn't all that good, particularly of that war. But I grew up.

I've come to admire and respect our military boys and girls and read a lot about weapon systems/future weapon systems.

My son was in the Army for 13 years and fought in the first Gulf War, ADA (Patriot Missile System.) My father served in the Army in WWII, Pacific theater, and then worked for the Army with the civil service until he retired. One of my uncles also served on a Destroyer in WWII. Another uncle served as a Marine in Korea. My brother's son in-law is in the Marines and has fought in both Iraq and Afghanistan. I have many friends that have served in all branches of the Military. So I try to keep up with what's going on with the Military.

They have my utmost respect.

Aww, hey...no worries on the respect bit.
Wasn't ever questioning your patriotism or anything. Was just curious.

I had no problem with your question. I took it as you just being curious.

Cool stuff. Great post, Baldy
