Reminds me of GUNS-A-GO-GO the gunship Chinook combat tested in Vietnam.
I would recommend that for those interested in detail and historical accuracy that you actually make a Grokipedia account. That will allow you to offer corrections to improve the site (just as Wikipedia has done for years).
I've already suggested a couple detail improvements for the CH-46 page. With more to come.
The info I found stated it was a missile launcher, but it sure looks like recoilless to me!
Here's one mounted under an A-4.
And another USMC proposal to mount under an OV-10.
Here’s an oldie…maybe even grandpa to some tandem rotor developments, the Bell HSL-1.
The Bell HSL was powered by a single Pratt & Whitney R-2800-50 radial engine, a double-row, 18-cylinder, air-cooled piston engine rated at 2,400 horsepower. It was a clean sheet design utilizing advanced anti-submarine warfare (ASW) equipment to fulfill its primary role in detecting and engaging submerged threats from naval vessels. In the end it proved too expensive to build. AFIK it is Bell’s only journey into tandem rotor design.

Four generations of Piasecki/Vertol/Boeing.

Del Mar DH-20. A foldable mini med-evac tandem rotor helicopter.
The DH-20 was a proposed design for an easily portable med-evac chopper from 1968. It was designed to carry a pilot and up to two passengers and operate in areas inaccessible by normal sized helicopters. It was also designed to fold up somehow, maybe it was more collapsible than foldable. Since the need for such an aircraft declined, the DH-20 was never put into production or flown operationally.
No apologies... I Love Tandem Rotor Helicopters!!!
During the '50s through'70s there was worldwide interest in Tandem Rotors.

Filper Beta 200- A tandem rotor helicopter using the "Gyroflex" system, special balance weights fitted to the roots of the rotor blades. First flying in 1966 with only 3 built.
McCulloch MC-4 Light Helicopter (1951) Crew: 2, Powered by: 1 × Franklin O-335-6 (6A4-200-C6) Piston Engine Horizontally Mounted Amidships and Powered 2 Intermeshing Tandem Rotors, Rated at: 200 hp – Range: 200 Miles, Maximum Speed: 105 mph
And evne the Chinese are getting into the tandem game.
Funny you should say that...two days ago during our morning brief, one of my co-workers looked up which way a rotor turns on the EC-130 after talking about how AI gets so much stuff wrong. Grok said both the A-star and -130 turn counter-clockwise (a familiar discussion from a week ago here). So he argued with it and it doubled-down on the "knowledge" and even clarified which way it turns (incorrectly) from both above and from the perspective of inside the cockpit. It then also said that Sikorsky helicopters turn clockwise.
At that point we lost interest.
Like what?
They briefly owned Schweitzer and unloaded them because light helos are just a tough place to make money.
There’s a reason that Robinson builds everything around the same basic airframe. Both the 505 and the 407 leverage the original 206 certification. Designing a clean sheet small helo is unlikely to ever make its development cost back.
They’ve got to make the 60 pay off longer by offering things like the U-Hawk and installing MOSA. They’ve also got to get people to buy their X2 tech.
The second one is hopeless—everyone knows X2 sucks. So they are leaning even more into the 60.
Yeah…Parlin Field, 2B3. The NHARNG aviation detachment does a lot of practice work at that field. I’ve flown in there a few times. It is a nice, old fashioned airfield with a friendly FBO offering that kind of coffee that’s been in the glass pot for a few days.
Historical Side Note…the land the airfield is on once belonged to the last surviving Revolutionary War soldier in America who died at 101 in 1861!
