someone elsewhere suggested that Oz is currently looking at modifying OV-10 Broncos to fly off the new LPH helicopter-carriers - surely that would make those ships horse-floats ??  :-\

Would like to see the prodution-line started up for them again ;)
But probably end up with the same stuff-up as the Seasprite project.

ummmm........ I commented to the RAEME WO2 in charge of the Tigers maintenance team that I had seen one flying earlier in the week and he said  " Sshhh....don't say that you'll jinx us and we'll end up with them all US again."  Needless to say he is not a fan.  Then again it hasn't done too bad for a developmental platform, sold as MOTS, to an unsuspecting military.

Don't get me wrong, the Tigers have had their issues...but going back to a 1950s/1960s design that has never served in the ADF and which is largely out of service elsewhere?  That is plain ridiculous!

Like the Sea Sprite?  ;)

I like the Tiger and believe it would have made more sense if it was either replacing an existing type, i.e. AH-1 J or S or if the requirement was for 2020, or if we were looking to be a full development partner.  The way it was selected and contracted just demonstrates how broken our procurement system is.

Back on topic, how about a Nomad / Bronco hybrid?

The worst of both designs? 

The Tiger was a compromise.  The Army wanted Apaches, Treasury wanted R-22s.  They ended up with the Tiger.   Personally, I've always liked the Mangusta.

Getting back on track, an Australian OV-10 back in the late 60s/70s/80s would certainly be a different proposition.  Perhaps starting with the RAAF and then eventually transitioning to the Army in the 80s.  Perhaps starting off with a small buy during the Vietnam war.  I would look to the Hueys, Nomad and/or Caribou for possible schemes.

Original layout with short-span wings, note it can be built from the old Hawk/Testors 1/48 kit by simply
shortening the outer wing panels. What can't be built from the kit OOB is an accurate production aircraft.
On the production aircraft not only were the wings lengthened, the booms were moved outboard by six
inches, the Hawk kit has the boom spacing of the original prototypes.
 ;D

Also note the "flat" sponsons and that they were removed when the floats were mounted.

Edo floats too, so there's a very good build possibility ----- hmm! just need to work out the length.  Khee Kha do a few Edo float accessory sets.

Bronco with tail hook, mine-sweeping drogue (deployed from open rear doors) & blue/white cam ???

A Tiger in blue/white or another naval scheme (anything other than grey) would make a nice whif too.

Oh, THAT Tiger.  :(

Not exactly the prettiest helicopter in the world, is it? Give me an OV-10 variant any day, especially the CV-10.

I got a reply from Lars, he's going to see if he has something that will work.  Meanwhile I did some number crunching, I've found an interesting bit of trivia, the empty and max take-off weights of an OV-10A are very close to a Bristol Bolingbroke (Blenheim) and I've already got a project on the go for the floatplane variant of the Bolingbroke.  Checking the length of the float I've done from a 3-View of this aircraft I got from John Adams (Mr. Aeroclub), I find the float is about the same length (33'-6").  Looks like I've got some casting to do if Lars can't help.

I noticed that these aircraft had four bladed props and a "hump" on top of the rear of the center fuselage. I wonder what other visible mods there may be. Would the new props be attached to new engines?

The "hump" looks to be the ALE-47 that the article mentions and I believe the 4-bladed props are associated with the engine upgrade that came in with the OV-10D.  While they stayed with the T76/TPE331 engines, they went for a much later and more powerful version than fitted to the OV-10A.

The ALE-47s are chaff/flare units on the outsides of the tail booms.  They look like black squares in the mentioned link photo.

The hump is/was a mount for he ALQ-144 "Hot Brick" IR jammer.


The two OV-10G+ airframes tested also had full glass cockpits and a different FLIR/EO ball under the nose than the standard OV-10D/D+.  Got pics somewhere.............
