Because it contradicts what you are saying about ramjet designs where you need to sacrifice speed for range and vice-versa perhaps? Like how some sizes remained the same with a bump up in speed and range? Klevok-D2 is a ramjet design that just happens to surpass its predecessor design like the one I have mentioned.
Firstly, I still don't understand what you are comparing the UAV to?
Secondly, you don't understand my point when I said ramjet engine can scarify speed for range. A ramjet engine like any air breathing engine, can adjust its thrust by changing the fuel flow rate. This ability to control the fuel flow is called the throttle ability. If target is 20 km from your aircraft then the thrust is very high for high speed and high acceleration. If target is 200-300 km from your aircraft then the thrust reduced for sustain. You can think of a ramjet missile as a tiny aircraft, imagine you are a pilot of an interceptor, when the target is 100 km from your airbase, you can pull full afterburner to intercept it, but if target is 2000 km from your airbase you have to cruise at subsonic speed or you will ran out of fuel before you get there. Ramjet missiles do the same thing. How much your missile can reduce fuel flow depend on a quantity called the turn down/throttle ratio, the bigger this ratio is, the wider range of thrust that your missile can operate at. You can bump up the range by increasing this ratio but at the maximum range the ratio is at maximum and cruising speed at the minimum and vice versa. The big advantage of ramjet missile is the ability to control the speed.
Sources like this say that?

"The version which will be fitted on Tejas will be called BrahMos NG (BrahMos Lite) and it will be much lighter although the payload will be the same."
Have it occur to you that this is just another example of a journalist who doesn't know what he talking about?. Just like earlier example when he think the thickness of Salisbury screen is 1/2 wavelength.
Brahmos NG diameter is 20% smaller than BrahMos , to suggest their warhead is the same is laughable
Yup, but there are ramjets that hit mach 5 as well.
and?.
Whatever makes you feel better I guess.

"The existing Russian supersonic cruise missiles will be improved by increasing their range and bringing the speed to hypersonic. This was announced in an interview with TASS by the general director, the general designer of NPO Mashinostroyenia (part of the Tactical Missile Arms Corporation) Alexander Leonov."

"Expert: onyx-M missile tests with a range of 800 km have already been carried out. According to the chief editor of Arsenal of the Fatherland magazine Viktor Murakhovsky, the range has been increased due to the new fuel composition, as well as a lighter and more compact onboard radio electronics."
There is a lot of ambiguity in his comment and what concluded by the journalist. Moving in general direction is a big different from achieving these goals. You don't increase the missile speed to twice as high without changing the aerodynamic and propulsion system significantly
- How do you see the directions for improving cruise missiles, and in particular, how will Onyx change?
- The general trend towards the improvement of cruise missiles is an increase in speed to hypersound, an increase in the range, as well as the versatility of the missile, both in terms of its goals and the launch platform used. We are moving in this direction.
Like I said it deals with air density better.
Who say it doesn't?
Pretty much you are re-iterating the same responses of onyx and brahmos are not this or that when I have already responded to those responses with more sources. Brahmos-2k comes with a 1st and 2nd phase developments, that's a yes. But I am having a hard fucking time copy and pasting the old source which states same ramjet but increasing to mach 5 speeds with more range.
https://idrw.org/india-plans-two-hypersonic-brahmos-2k-version-of-the-cruise-missile/ see the 2nd sentence in the 2nd paragraph, than see the last paragraph and last sentence. Than at that point your probably realize that the brahmos version they are getting upgraded has a uncanny resemblance to the two Tass sources I have posted earlier here regarding the Onyx-M speed and range(Holy shit what a coincidence). Believe what you want about the Klevok-D2 but that does not change what the missile corporation statements about that missiles improvement over the Hermes.
Look at their references:
According to source closed to idrw.org What source? a guy down the street?. That hardly strike me as reliable.
Secondly, you still don't understand my point. Just because you can improve top speed doesn't mean you escape from the relationship between range and speed that I explained earlier. For example: F-4 top speed is Mach 2.23, combat radius is about 840 km, for comparison F-15 top speed is Mach 2.5 and combat radius is about 2037 km. So F-15 can fly faster and further than F-4. But that doesn't mean F-15 can fly 2037 km at Mach 2.5. A ramjet missile is very similar. You can make a ramjet missile that has higher top speed and range than the previous version, but for any given shot, it is a trade off between range and speed, you can either have long range shot or very high speed shot, but not both at the sametime. Because when target at long range, missile will throttle back to save fuel, that affect speed.
SPEAR was only mentioned because it was the USN requirement and that the current AARGM-ER despite what Stuart has said wont do since the USN was looking for a ramjet design of the agm-158. Either way with SPEAR being planned for a wider internal weapons bay like the F-35C and that orbital OTK designed a internal weapons bay weapon getting close to hypersonic speeds but they still need a ramjet besides the claimed specs made.
AGM-158 is JASSM, a subsonic stealthy cruise missiles with turbojet engine
AARGM-ER is an extended range, higher speed, internal bay version of AARGM
SPEAR is a separate program from AARGM-ER
