I read that in the Vietnam War days the US Army evaluated the Grumman Ag Cat as a convoy escort aircraft. They decided it was just what they needed but if they bought a biplane they would be laughed out of the Pentagon. Since reading that I have often thought that crop duster aircraft would make good light attack aircraft for "limited war" environments. Well, it finally has happened!

From Avweb:

"The U.S. Special operations command has chosen an armed-to-the-teeth version of the venerable Air Tractor agricultural application aircraft as its new counter-terrorism platform in its Armed Overwatch mission. The AT-802U Sky Warden was chosen over two other finalists, the Textron AT-6 Wolverine, based on the Texan trainer, and Sierra Nevada Corp's MC-145B Coyote, a high-wing twin based on the Polish PZL M28 Skytruck. In the end, it was the brawny Air Tractor's payload capacity that likely tipped the balance, according to Forbes.

It can carry the Common Launch Tube, which can fire missiles, launch drones and small munitions and features a sensor suite integrated by L-3 Harris. The mission of these aircraft is to drop into trouble spots with little fanfare and even less support on the ground. Something else that distinguishes the Air Tractor is that it's a taildragger, likely the only one in the inventory. Forbes did the math and figures the Sky Warden costs about $20 million apiece. It's not the first non-agriculture application of the Air Tractor. Its Fire Boss variants have become the industry standard for Single Engine Air Tanker (SEAT) aerial firefighting aircraft."

They will buy up to 75 of them, to be built in Olney, TX and then modified in Tulsa OK by L3 Harris. Taildraggers forever!

Although I love the look of this, I do hope who ever operates these aircraft has a robust training program should potential candidates be taken from the USAF ranks. I worked on a program where USAF IPs were assigned to fly a tail dragger motorglider, it didn't turn out so well!

Tail draggers (although fun to fly) disappeared from combat aircraft design many years ago for several different reasons. I'll leave it at that!
 
The Caravan was built to fly straight and level at medium altitudes, hauling stuff. By its nature a crop duster has to be able to handle tight turns and maneuvering close to the ground without stall and spinning. And I don't know how aggressive you can be with shoving the nose down on a Caravan but I'm sure the Air Tractor is better at it.

The design of the first dedicated crop dusting airplane was by Fred Weick, designer of the Ercoupe, after he left ERCO and went to the Univ of TX. Virtually all further such aircraft have followed that same basic concept. After that, he went to Piper and led the team that designed the Cherokee.

Is is a stick shift thing?
 
They are cool looking.



 
If a pilot cannot fly a taildragger, he/she shouldn't be flying. End of story.
 
I've seen the USFS' AT-802F in action.
It's incredibly agile.
When I was a youngling, I would watch the local pilot fly his Air Tractor crop dusting the fields that are now fancy developments in Phoenix, Az. The way he went from end to end and flipped that thing around for the next row always reminded me of a pendulum, fly low, pull up hard, right before it seemed it would just fall out of the sky it's flip around and repeat over and over. For my money, it was a lot more entertaining than watching the guy with the helicopter from MASH doing it BUT I'll give it to the chopper pilot, he was Aces when it came to landing on the tank truck! That was in the '80s, looking back, I'm sure that guy must've honed his skills where and when it counted.. loach or snake!
 
Wolfgang Languishe: "Rudders are put on airplane to make up for the mistakes of the designer."

My Ercoupe has not one but two rudders, coupled to the ailerons with no rudder pedals. I have some tailwheel time, but I prefer my 1946 airplane.

Funny thing. I arrived at the airport I use today on a Saturday. The next day I thought I would fly around the area a bit. I taxied down to the end of Runway 29, did a run-up and then watched a Cessna 140 come down final and land. I checked for traffic in the pattern, and when assured all was clear I looked down the runway to see if the 140 had turned off yet. It was still on the runway, sitting on its nose. The pilot had feared he was drifting too far to the left side of the runway and hit the brakes. The 140 did what the earlier model 140's are known for, the ones before they moved the gear forward, and went over.

The Ercoupe is a unique and great little aircraft
 
From what I've seen (read), the AT-802U/AT-802L is packed with an electronics suit that dang-near rivals an A-10.
I haven't seen any particulars on armor, but it has been mentioned, so it seems that the militarized Air Tractor is a formidible machine.

The other types they're fooling with, I have no idea, to be honest.
