- The Martin P5M Marlin, designated P-5 Marlin after 1962 was a twin-engined flying boat that entered service in 1951 as a successor to the PBM Mariner from the same company and served into the late 1960s with the United States Navy on naval patrol duty.
The aircraft pictured were serving with VP-40 during Operation Market Time at the end of July 1965, a joint effort by the United States Navy, Republic of Vietnam Navy and Royal Australian Navy begun in 1965 to stop the flow of troops, war material, and supplies by sea, coast, and rivers from North Vietnam into parts of South Vietnam during the Vietnam War. The extra thrust from the Rocket-Assisted Take Off bottles allowed the aircraft to take to the air with a greater load of fuel than could normally be carried which extended their range on patrol.
The vessel visible is USS Currituck (AV-7), a WWII-vintage seaplane tender and lead ship of her class that also included USS Salisbury Sound (AV-13). Both vessels participated in Market Time maintaining the flying boats during their patrols, although these would be phased out within less than two years to be replaced with land-based aircraft like the P-2 Neptune and P-3 Orion.

I’m a Navy/USMC flight test engineer at Patuxent River, MD. Our base still has concrete ramps where seaplanes were pulled out of the water. The old protected mooring area is still there although after all the wave action and storms the concrete is crumbling. I don’t doubt much of the flight characteristics were documented here. I’m gonna have to do some documentation exploring to see if I can find anything. Thanks for the awesome videos!
@@drott150 thanks!
Bring seaplanes back!!
Japan has some fantastic military sea planes. Actually they just came out with a new one that is so modern the U.S. is buying some for the Coast Guard. The US-2.
The Japanese have a four engine turboprop version that is AWESOMELY AWESOME!!. Why we don't have one escapes me.
"Strap a rocket to it" seemed like the go-to answer if they couldn't get something completely off the ground back in the 1960's....
There's one in the National Naval Aviation Museum at NAS Pensacola. I was just there yesterday. It's a monster and just towers above you.
Cool! And thanks for the inspiration, I think Market Time will be tonight’s interest!
The Navy has actually put in a contract with catalina to make a modern PBY,as a new long range slow speed search and rescue/ interdiction aircraft with long loiter time

WOW!! Great video. Many thanks for posting it. As an early 70's Cold War Submarineer, I have a second hand story about a Tang class Submarine and a Navy flying boat, if anyone is interested in hearing it??
please share!
@hw97karbine Thank you for the response.. Let me check and research the NavAir and Diesel Boat Navy of that time to build the basis of that real world no shi**er sea story to hand off to everyone here.. The technical prelude is what's best understood. So be patient, everyone 😌 . I will make it worthwhile..
@hw97karbine The following has to do with the pejorative ryme ditty of the U.S. Navy Submarine Service from the 50's, "HARDER, DARTER, TRIGGER, TROUT, ALWAYS IN AND NEVER OUT" Whose heard of that one before?? Without online searching it??
Okay, I did some cross checking of some online sources and with an older fellow SubVet. This story centers around the first four of six post WWII TANG class submarines built with innovations gleaned from the captured German type XXI boats. The first four boats as built had the GM 16-338 verticle pancake engines. Horribly unreliable. The Navy refused to use the GM recommended lube oil and used standard lube oil. They were very high RPM engines and leaked oil down into the DC generators, causing shorts and grounds and were hard on their internal parts. Three of the six boat were assigned to Pearl Harbor. The first to go were the TANG and WAHOO, with their initial pancake diesel engines. So, as I remember, this is the story I heard from a GUDGEON SubSailor. GUDGEON was the third boat to be assigned to Pearl Harbor and was built with Fairbanks-Morse engines. The story goes, either TANG or WAHOO were approaching Hawaii limping along submerged on only one of the four engines. The other three were inop. The conversation between the Control and Manuevering went like this.
Con, Manuaver..
Con Aye,
Request all STOP
Con Aye, All STOP
Manuavering Con, state the reason
for requesting All STOP?
Con, Manuavering, we just lost the last engine..
So, they surfaced Radioed SubPac at Pearl Harbor stating they were dead in the water at ×××.×××× And we need a new crank shaft to make it in. So, thankfully, the Navy still had Martin Flying Boats and PDQ, they flew one out, and the Engineman installed the new crankshaft. And they limped on in to Submarine Base PH.. (As soon as possible, the first four boats TANG, TRIGGER, WAHOO and TROUT were put into the yards, cut in half lengthened and more reliable appposed piston Fairbanks-Morse engines installed. Since HARDER and DARTER were built with Fairbanks-Morse engines to begin with, I guess their names were chosen because they were rymeable and TANG and WAHOO didn't (And DARTER was in it's own class, similar to the six TANG class but different enough to be in its own class).
@hw97karbine I've posted a reply twice, but it keeps disappearing.
@@covertops19Z I can't see any comments so something in the text must be tripping up the algorithm, unfortunately I have no control over it.

Arizona desert legend before Meth/Crack/etc. Two guys who had fried their brains in the Arizona Summer heat, strapped a RATO to the top of an old car. They lined up on the straightest and longest piece of road they could find and ignited the RATO. Everything was alright until they encountered the first bend. The tire slicks showed they'd braked, but the path they tore through the desert ended at a burning cliff face and debris field. The desert fire they started led to their discovery.
So cool would have loved to have seen them fly.
