Anti-Leviathans Ground/Sea guns?

[StCptMara]

So, we know that in real life, we can shoot down aircraft, and I got the impression from the few stories we have so far that Leviathans are not actually very high in the air. This leads to the question of: Can guns be built using the existing technology in 1910 that can shoot down a Leviathan from the ground, or from a sea going platform? From the first story posted on Monsters in the Sky, I got the feeling that the guns on existing wet-navy ships had certain weaknesses(namely, the limit to their elevation) against Leviathans. But, can that be compensated for?

Additionally, when/if submarines are developed, it would seem an advantage to be able to surface,  fire an Anti-Leviathan Gun a couple times(or even an early model Sub-Launched Rocket that could hurt a Leviathan) and then dive again. Should we be expecting devious minds in R&D to be trying developments like that?

Devious minds are trying to develop everything from submerisible leviathans to the infamous electroid bombe. Doesn't mean the ideas will work

And it may be worth doing a little investigation into the state of anti-aircraft artillery in 1910, or even 1918. In short - it sucked worse than a second-hand vacuum cleaner, and was ineffectual even against zeppelins. And that's after several years of total warfare.
