USS Midway (CV-41) – The Midway class aircraft carrier was one of the longest lived carrier designs in history. First commissioned in late 1945, the lead ship of the class, USS Midway was not decommissioned until 1992, shortly after service in Operation Desert Storm in 1991.

The CVB-41 class vessels (then unnamed) were originally conceived in 1940 as a design study to determine the effect of including an armored flight deck on a carrier the size of the Essex class. The resulting calculations showed that the effect would be disastrous for air group size. The resulting ship would have a maximum air group of 45, compared to 90–100 for the standard Essex class fleet carriers. As a result, the concept went to finding a larger carrier which could support both deck armor and a sufficiently large air group. Unlike the Royal Navy’s aircraft carriers, for which the armored deck was part of the ship structure, the Midway class retained their "strength deck" at the hangar deck level and the armored flight deck was part of the superstructure. The weight-savings needed to armor the flight deck was acquired by removing a planned cruiser-caliber battery of 8-inch (203 mm) guns and reducing the 5-inch antiaircraft battery from dual to single mounts. They would be the last USN carriers to be so designed; the size of the Forrestal class supercarriers would require the strength deck to be located at flight deck level.

The resulting carriers were very large, with the ability to accommodate more planes than any other carrier in the U.S. fleet (30–40 more aircraft than the Essex class). In their original configuration, the Midway class ships had an airwing of almost 130 aircraft. Unfortunately, it was soon realized that so many planes was beyond the effective command and control ability of one ship.

While the resulting ships featured excellent protection and unprecedented airwing size, they also had several undesirable characteristics. Internally, the ships were very cramped and crowded. Freeboard was unusually low for such large carriers. In heavy seas, they shipped large amounts of water (only partially mitigated by the fitting of a hurricane bow during the SCB-110/110A upgrades) and corkscrewed in a manner that hampered landing operations.

None of the class went on war cruises during the Korean War. They were mainly deployed to the Atlantic and Mediterranean. During the 1950s, all three ships underwent the SCB-110 modernization program, which added angled decks, steam catapults, mirror landing systems, and other modifications that allowed them to operate a new breed of large, heavy naval jets.

All three of the Midway class made combat deployments in the Vietnam War. Coral Sea deployed to the Gulf of Tonkin six times, Midway deployed on three occasions, and Franklin D. Roosevelt made one combat deployment before returning to the Mediterranean.

In the late 1960s, Midway underwent a massive modernization and reconstruction program, which proved to be so controversial and expensive that it was not repeated on the other ships. By the 1970s, Franklin D. Roosevelt and Coral Sea were showing their age. They retained the F-4 Phantom II in their air wings, being too small to operate the new F-14 Tomcat fleet defense fighter or the S-3 Viking anti-submarine jet. In 1977, Franklin D. Roosevelt was decommissioned. On her final deployment, Roosevelt embarked AV-8 Harrier jump jets to test the concept of including VSTOL aircraft in a carrier air wing.

Coral Sea was rescued from imminent decommissioning by the election of Ronald Reagan in 1980. Reagan’s proposed 600-ship Navy gave the remaining ships a new lease on life. Coral Sea underwent extensive refits to address the ship’s poor condition. When the F/A-18 Hornet became operational in the mid-1980s, the Navy quickly deployed them to the Midway and Coral Sea to replace the older F-4s. A 1986 refit for Midway bulged her hull to try to increase freeboard. While successful in this regard, the bulges also resulted in a dangerously fast rolling period that prevented Midway from operating aircraft in heavy seas. The bulging was therefore not repeated on Coral Sea.

The Reagan Era reprieve could not last indefinitely. In 1990, Coral Sea, which had long since earned the nickname "Ageless Warrior", was decommissioned. Midway had one last war in which to participate, and was one of the six aircraft carriers deployed by the U.S. against Iraq during Operation Desert Storm. A few months after the campaign, the last of the class left Navy service.

Coral Sea was slowly scrapped in Baltimore as legal and environmental troubles continually delayed her fate. She is likely to have been the last large warship ever to be scrapped in North America. One decommissioned supercarrier, America, has been sunk in deep water after undergoing destructive battle-damage tests, and the Essex-class carrier Oriskany was scuttled off Florida as a diving reef; this is likely to be the fate of their

Shooting Snowflakes

I originally wanted to do a photo with my globe as a tribute to the environment and to ‘spread awareness’ about the issues it faces these days, but I didn’t like how they turned out, so I thought it would be best to put a photo of nature instead. This is an old photo… I love winter.

If you read this, thanks.
If you don’t, I don’t care. I’m just putting my thoughts down. You might agree with me, roll your eyes, be somewhere in the middle, or not even give a crap, but this is what is on my mind at the moment.

I’ve just been thinking.. kind of about, well.. everything. But mainly about the world. It keeps me up at night. You don’t have to read this, it’s more of like a journal entry to the journal I’ve never had.

… I’d been dreading and putting off reading a summer assigned book for my IB Environmental Science class, but I finally made a small dent in the material. It’s pretty much all statistics so far, which I though would be extremely boring, but I found that instead of boring me, the facts shocked me. I put a star next to the ones that really got me, and will share them here. I mean we are always hearing about environment issues and how we need to do something before it’s too late.. and so on.. but I feel as if a normal-minded person like myself can’t possibly think of a way to save this planet. Of course recycling is do-able, and so is carpooling, or buying environment friendly things such as reusable bags, but how can small things like this save our home from all of the terrible detrimental acts we’ve created? It just makes me scared, not necessarily for my life, but for the future generations that we are putting these burdens on. Some eye-opening facts…

*It took all of human history for global population to expand by 1900 to a billion and a half people, and today we have over 6 billion.
*One calculation suggests that more energy was consumed in the last 100 years than in all of previous history.
* In 1960, 5% of Marine fisheries were either fished to capacity or over-fished; today 75% of marine fisheries are in this condition.
*A forth of the bird species are extinct and another 12% are threatened.
*25% of mammals and reptiles are threatened, and 30% of fish.
*The rate of species extinction today is estimated to be a hundred to a thousand times the normal rate at which species disappear.
*a third to a half of the world’s forests are now gone.
*each year human societies are destroying about 40% of nature’s net photosynthetic product.
*a fifth of the world’s people lack clean drinking water, and 40% lack sanitary services.
* Over the next two decades, the average supply of water per person will drop by a third.
*In the past 20 years, global energy use is up by 40%, global meat consumption is up by 70%, and global paper use is up by 90%.
*Close to half of the world’s people live on less than two dollars a day.

All of these facts were only in the first 20 or so pages of this book, and I’m sure there are many more horrifying ones to come, unfortunately.

Anyways, us humans are capable of so much, and I am a bit frustrated with what we have done to our planet. And even though I may not see the effects first-hand, I also personally feel responsible for what is happening. I can’t help feeling guilty when I take 20 minute showers, when I should be conserving water, or drive in a car knowing it’s bad for the environment, or sit in my nice air-conditioned house stuffing my face with dinner when there are people in third-world countries starving and dying each day from malnutrition.

So just putting my two cents in:
One: People need to freaking control themselves and stop having so many kids. The world is WAY too populated and we are using up all of our resources FAST. And we need to educate people in other countries like Africa to stop producing kids that they can’t feed.
Two: Finding some way to stop global warming, or at least decrease it. And for those people who don’t believe in global warming and say "it’s just natural for the Earth’s temperature to fluctuate"… I’m sorry, I find that completely mental. There has been so much damage done to the planet in the past 100 years, with the Industrial Revolution and cars, and what not, that it makes sense why the Earth is heating up, and glaciers are melting, and making Polar bears extinct.

Oh, and one more thing. And I’m not just saying this because I’m a vegetarian. COWS. Cows are ruining our ozone layer. SERIOUSLY. Livestock is responsible for 18% of greenhouse-gas emissions worldwide, according to the U.N. Who would have thought that cow’s farting could do such damage And I’m not implying that we kill off all the cows in the world, it would just be sensible to stop over-breeding them. But I doubt that will ever happen, because people enjoy their steaks and hamburgers far too much..

I could go on, but I won’t. Sorry for rambling.
