I posted last week about why huge bipedal fighting ‘mechs’ from sci-fi like Pacific Rim are unlikely, unless the laws of physics change.
But that doesn’t mean sci-fi mechs have to be boring. Not at all.
More in a moment. First off – what’s wrong with a 120-metre x 20-metre biped mega-mech? Alas, even if you could get your mech to move, it’s a 2400 square metre target balancing on pivot points wa-a-a-ay below its centre of gravity. There are reasons why soldiers don’t stand tall and walk very, very slowly towards the enemy. When it was tried, on the Somme in 1916, the British Army suffered its heaviest one-day losses – ever.
The same’s true of real mechs – main battle tanks. In the First World War, infantry tanks were high-sided. The fact that height made them targets was understood, But the design committee couldn’t compromise on the height of the tracks, because the criteria was for a vehicle able to drive over trenches – dictating a rhomboidal profile equivalent to a 20-metre diameter wheel.
Inter-war tanks had different criteria but were still high-sided. Then, during the Second World War, sloped armour – again, well known in naval circles – was applied by Mikhail Ilyich Koshkin to his T-34. Modern tanks follow that lead. Tank tactics reflect ‘low is better’ too – a commander looks for places to go hull-down. You can’t do that in a 120-metre high bipedal mech.
So does this mean mech sci-fi has to be dull? Not at all. I’m thinking of the most awesome mech I’ve ever seen in SF – Stanislaw Lem’s Cyclops. Total badass. To one reader, ‘goddamn dynamite, I mean, like whoa.‘
Get this. Lem’s Cyclops is an autonomous robot weighing 80 tons, 25 feet high, levitated on force fields, protected by ceramic armour and energy fields, with near-inexhaustible energy reserves. It’s armed with an antimatter cannon capable of continuous fire in all directions – annihilating everything in a constant nuclear-yield detonation, soaking the battlefield in relativistic-scale energies and lethally hard radiation.
It’s from Stanislaw Lem’s The Invincible (1964). I read that novel in 1978 and – setting aside Wendayne Ackerman’s peculiar translation from Polish, via German – it’s total OMG. Mech-machine evolution…versus humans. And Lem also envisaged the ultimate end; a robot fly (‘grey goo‘). Tiny, individually disposable, always replaceable – available in multi-billions – and able to connect into swarms that were …invincible. Blasting them was like fighting the ocean with swords. The logic pivoted on energy consumption.
That was the ultimate sci-fi mega mech. Infintesimally tiny – yet, vastly huge. Expendable, yet indestructible. Brilliant. But then, Lem’s stuff always is. Here’s part of the sequence where the Cyclops goes into combat with the flies. Lem is one hell of an author! Don’t just take my word for it. Find a copy of that book and read it – because, my friends, Stanislaw Lem has shown us how mechs are done.
And – more importantly – how we’ll relate to them.
