Real hurthling! posted:why do mortars make a cool fwump sound when they launch in movies instead of a boom? Mortars have a muzzle velocity around 90 m/s, howitzers fire at 830 m/s. It's similar to how a silencer for a pistol reduces muzzle velocity below the speed of sound, so you could think of a mortar as a tiny silenced howitzer Speed of sound is around 350 m/s

This is due to the fact that customers expect quiet cabins but quiet cabins reduce the amount of engine noise you can hear.

Eh eventually electromagnetic will be better than steam and it won’t get there without a lot of work and a lot of Virginia McMansions. Steam catapults are a mature technology now, but didn’t arrive overnight.

Remulak posted:Eh eventually (Science Fiction) will be better than (equipment in service) and it won’t get there, but will buy a lot of Virginia McMansions. Development began in 1946, and the first operational steam catapult to be installed on a warship was in 1950. This is what they have said about every boondoggle for the past 30-40 years including chemical lasers, rail guns, Electrothermal-chemical technology, Bulk loaded liquid propellants etc. etc.

Better question is whether heavy fixed-wing carrier aviation is really going to be of strategic importance in the future. Drones (or, rather, fundamentally disposable aircraft) obviously do, and it's hard to imagine a world in which imperialistic forces wouldn't be interested in amphibious warfare, but carriers for big, heavy, manned fixed wing strike and fighter aircraft are big fat targets in a world that includes ballistic anti-ship missiles. Like does it matter whether your aircraft carrier uses the new hotness aircraft launching technology when the billions and billions you've invested in it, its air wing, pilot training, etc. gets pasted by a missile if it comes within striking distance of a hostile coastline?

There are many things you need warships for, and the utility of those roles will keep them in service. In war, nothing is invulnerable and everything is a target, you just have to do what you can.

yellowcar posted:i would go even further and say that any surface vessel is basically a big fat target for the cheaper anti-ship ballistic missiles Your analysis has deep flaws. You hit an issue where the combat modelling within what was a high-level political/strategic wargame used some very simplistic assumptions for speed, rather than doing a realistic analysis of the tactical battle (which can be done, and in considerable detail, but takes a day or two at least to tailor and run for the specific engagement… which makes the turns too slow). Red didn't have to provide any information of how this massive missile armada was being assembled, briefed, positioned, targetted and delivered in a precise simultaneous time-on-target raid; in less than a day; without using radio; let alone the very real problems of mutual interference (how many missiles are trying to use the same radar frequency to detect and home on their targets?) One version described was that rather than go for a realistic "an AEGIS cruiser can defeat <very many> incoming missiles" representation - which was the job they were specifically designed for, but basically made Red's antiship missiles of very limited value - a much lower value was assumed to overwhelm the defenses if the ship was caught flatfooted at short range, or left confused by a deceptive tactical picture. However, the much simpler and clearer situation of "Bruisers, sah! Faaaarsands of 'em!" where it's clear and obvious that a major attack is underway, and the AEGIS system is turned loose in automatic mode to do what it's designed to do. Again, having found a specific opportunity in the rules, Van Riper was very upset when it was challenged and questioned. Similarly, the carrier was "destroyed" by suicide-crashing an aircraft onto its deck, using the claim that a small single-engined Cessna would be able to get close enough without being shot down to then make a sudden, destructive kamikaze dive. Again, though, this hits the problem that the aircraft used weighs about a ton at most, and has a VNE (formally 'never exceed velocity', informally 'wings fall off very soon after passing this speed') of about 160 knots. The carrier regularly survives twenty- and thirty-ton aircraft crashing down onto its deck at similar speeds many times a day - it's called "landing" for its air wing - without damage, and historically (much smaller, less well defended, less well armoured) British carriers hit by real kamikazes in 1945 had been back at flying stations within minutes. The model didn't include a rule for this sort of action, so Van Riper claimed "sunk" and then protested unfairness when this was challenged.

The solution is probably going to be jam as many missiles on a vessel large enough to stay a decent amount of time at sea, more or less the "super frigate" concept that has been getting more trajection in recent years. I don't know if I want to call it for aircraft carriers yet, they still have range, but again the US has probably placed far too much confidence in its rapidly aging fleet.

I don't know if I want to call it for aircraft carriers yet, they still have range, but again the US has probably placed far too much confidence in its rapidly aging fleet. Well you touched on an issue that comes up at every naval architects convention on warship design. Whatever the ideal surface combatant and related doctrine is, it's not one that the MIC as it exists now can or will produce, so naval planners are stuck trying to fight a war with the last functioning surface fleet that the state was able to deliver before the 2000's. Remember too that the US is trying to equal the Royal Navy at its peak in terms of dominance and force projection without allocating 40% of the national budget or having taxes anywhere near the level they did, let alone direct control over production and procurement. It's a deeply compromised system, and every strategic, operational or tactical problem flows from that because those high level political and socio-economic problems are not up for discussion. So, considering that alternatives to "the navy of the 80's, give or take ships and aircraft retiring from age" (F-14, A-6, A-7, S-3, OHP etc.) require political will or industrial capacity that can't or won't be mustered, or reliability and functionality that the MIC can't or won't deliver on, they do sort of have to limp along with, to borrow from the first time we saw how the rot had set in, the navy they have, not the navy they might want or wish to have at a later time. If you rewind the clock, it took the USN a long time to come to grips with the emergence of Soviet nuclear cruise missiles, submarine and air launched cruise missiles, anti-ship missiles, conventional warhead cruise missiles etc. they never satisfactorily solved the problem of the Backfire or Soviet SSBNs launching from bastions in Soviet waters, that that was probably the most functional the USN ever was, aside from 1943-45. For the navy now to respond to an emerging tactical, operational or strategic problem requires a state that can facilitate that. There are naval designers and maritime architects with all sorts of interesting responses, from a focus on ECM and EW, possibly to the degree that there's a partial return to gun armament as missiles become inoperable, to much larger warships, larger missile batteries, new types of missile and CIWS etc. but where steam catapults went from a brand new theory to operational on a major warship in 4 years, even introducing a new gun into service will probably be a 20 year boondoggle.

It's loving insane to me that the most basic element of life in a steam navy is being neglected. I mean, the Victorians took it a little far by requiring captains to buy their own paint beyond the provided I think 4 coats a year, and the amount of brass that needed to be polished, the buff and white paint in tropical waters, but letting major warships rust is ...lol.
