Twin-Engine Deck Based Fighter (TEDBF)

What exactly are the modifications required to convert a naval Fighter Aircraft from Catapult based take off to ski jump ? Any inputs ? @Picdelamirand-oil
For the Rafale nothing at all: all Rafale M's have a three position switch to take off either from the ground, or from a CATOBAR, or from a STOBAR. This switch changes the behaviour of the FCS on take-off, there is nothing else to change because the constraints of a CATOBAR take-off are higher than those of a STOBAR take-off.

You mean except for the FCS characteristics , no other structural modification is required for such conversion from CATOBAR to STOBAR take off & I mean this not just for the Rafale M but any other Naval Fighter Aircraft ?

Yes you have
CATOBAR > STOBAR > Classic aircraft
For exemple the aim of the naval Typhoon was to be able to take off from a STOBAR, the CATOBAR was deemed impossible.
 
USA mainly beat Japan thanks to its silent service by halting raw material shipment...

It is like a fighter jet : you need troops on the ground to win, but without you can't.

To be changed : Rafale is now officially able to take off from ski jump.
US beat Japanese because
1) japanes lacks resources to fight a Giant like USU. Their only bet was distance from US mainland. This advantages negated the day US started setting up bases around japan.
2) US had an immense fleet of Battleships & AC, which played the crucial role.

Any reading material you'd recommend to get a better idea of the difference between a CATOBAR & a STOBAR Naval Fighter Aircraft ?
In STOBAR launch, the nose wheel has to take lot of load as the aircraft goes over the ramp. and all the oleos of the wheels suffer sudden and rapid extension. In case of CATOBAR also the same thing happens. So you dont need any additional changes to the wheels or the aircraft structure

Thanks for the information. In that case , except for the FCS , the same TEDBF which will be developed for STOBAR can then also function from a CATOBAR based AC then . Is this a correct assumption ?

I also wanted to same.
All catobar are stobar capable..
Reverse? Is stobar capable of catobar?

It's all to do with the strength of the landing carriage in this case.

Developing an aircraft for CATOBAR needs a much stronger landing carriage, including the airframe. But that comes with a weight penalty. So ADA has to design TEDBF with the weight penalty for it to become CATOBAR-capable right from the beginning.

Rather what ADA has chosen to do is, they will make TEDBF STOBAR-only for now, but they can modernise it for CATOBAR operations if necessary in the future. Alternatively, they are also keeping a new CATOBAR-capable stealth design as an option. So it's totally unnecessary to make the TEDBF 1 ton heavier than it needs to be for a capability that may never be used. Similarly, the TEDBF's landing carriage has to be re-engineered to be lighter if it's to be sold to air forces.

The N-LCA also uses a different landing carriage, it can absorb 5 times the energy as the air force version. But it's still not CATOBAR-capable.

Basically, the reverse is not possible if the aircraft has been designed for efficiency from the start.

Not really, silent service had a defective torpedo well into 1943. "From December 1941 to November 1943 the Mark 14 and the destroyer-launched Mark 15 torpedo had numerous technical problems that took almost two years to fix."

Underrated in the general public obviously, bit overrated historically. Not to say submarines aren't of supreme importance, it's just the US was really hamstrung by torpedos and tactics.

First 6 months of the Pacific War was the hardest and won by 4 carriers. Only 1 submarine(crucial, but only because the route and Hornet was messed up) did anything at Midway. The next year after saw that carrier number whittled down to 1 carrier.

It's not like Japan had any way of protecting the convoys from airpower after being outnumbered 30 to 4 in carriers.

You can win logistically or through combat, or you could be like the US and do both. Would it have been harder without submarines yes, was it not even close if Japan had infinite shipping? yes. Even with unlimited resources the IC of Japan was too small compared to the USA. Only the USSR and USA mastered mass production techniques for war.

This is the main reason US beat Japan.

It is the US silent service that halted the commercial japan trade fleet.
 
I mean Japan is obviously losing the war by 1944 start without subs sinking any trade fleet due to torpedos.
Their torpedoes suffer from a default : they were cruising deeper than intended. ie some torpedoes gone under the smaller ship wothout exploding.
Some, but not all.
And US subs captains were aware of that so change the selected depth of the torpedoes.

Here the results, only for US subs. They did't wait 1944.
