It wouldn’t be a reignition. It would be an ignition of the second stage. Such missiles with mutiple stages have programmable ignition points.
2 stage means booster sustainer.
So short burning but stronger booster, with longer boosting but weaker sustainer.
2/Dual pulse means it gets ability to fire motor pulses, independent from eachother sections, that missile computer can ignite on demand.
And there is no evidence the motor does that. It is a standard boost-sustain motor.
Two stage doesn’t always mean that. It can also mean that the single stage looks like this (different profiles at different lengths of the single stage):
Boost + Sustain = Single Stage (no control over the ignition)
Solid rocket (which could also be Boost + Sustain) + Another solid rocket (which can be Boost + Sustain too) = Two Stage (control over the ignition)
Yes was pointing out that a previous pilot who has used the Alarm system used the term free fall.
Interesting to confirm that, what altitude does Alarm climb too when loitering?

No, you are mistaking it now once again.
So let’s get this straight.
This is a dual stage missile
The stage means there is a separate part that detaches.
Then you have dual burn/thrust, that are commonly called 2 stages. They present different “stages” with different burns, just inside one motor, instead of having a separate section that falls off.
And you have dual pulse, that has 2 separate propelant compartments, that can be ignited on demand by the missile.
Now when it comes to ALARM, there is no 2nd stage
Looks at the 1 Russian Torpedo in game, they better gave the parachute to the alarm

Yeah, I got that. The above is “two stage”, the nomenclature the ALARM propulsion is described with in every source I could find about it. It was never called “dual thrust” or “dual pulse”. From the looks of the missile it looks more like a “dual pulse” than a “two stage”. So either everyone calls it wrong or it really is a “two stage” where the first stage doesn’t get discarded and is used as a lengthened exhaust pipe, which effectively would make it a “dual pulse”. But on both you have the control over ignition and the profie of the fuel layout (so you could give both stages a boost+sustain burn profile).
It would just (in my opinion to be true) make more sense to use the first “stage/pulse” to bring the missile to its rough target area, deploy the parachute and wait for the target to reappear. The moment it reappears you ignite the second stage and have a much better chance to correct and hit the target with propulsion instead of just gliding.
As can be seen in this RAF document, it does not reignite its motor
You can see lack of flame when it approaches target

Then why bother at all and call it two stage if you don’t care about ignition sequence or delay and just burn them as they come? An AMRAAM also has Boost+Sustain but is described as “single stage”. Every other missile I know too…
As i siad before, dual thrust/burn is often described as dual stage. Even if it does not fit the definition exactly, they are used interchangeably.
“Two stage” and “dual pulse” aren’t used interchangeable as they mean completely different things as you described above yourself lol
That’s why the notions “single stage”, “two stage”, “three stage” and so on and “dual thrust” and “dual pulse” exist. Every single one of them describes a completely different way of rocket propulsion.
I never said they are
Yes, they mean different things. It does not stop the misuse tho.
Now, what they need to do is stick an ALARM seeker onto a Meteor. :P
At least the EURAAM (which was never seen again) was planned with a (S)ARH seeker (30-40 GHz active and 8-13 GHz passive). I bet with a few modifications to its HOJ mode it could function as an ARM in both of these bands with an active lock-on at the end (like the modern versions of the AGM-88) at least :D

For example here

Is PYTHON 5 two stage? No.
Perhaps specifying it is a two stage motor, not missile, players a role here, but who knows.
Meh… I hate it xD
But thanks for your patience :)
