Are 155mm artillery pieces taking over from 105mm's?

In a war like Ukraine with well established roads I would want to be in one of the wheeled howitzers with an autoloader. Those are the quickest to shoot and scoot with SP's second, there is not a single confirmed kill of a HIMAR and they are shooting off rockets with big smoke trails but they can displace very quickly. Something like Archer can also, a couple of minutes to pull in, fire and pull out.

I used to service a lot of 105 mortars on Stryker Vehicles.
Great fire control system and they shoot and scoot .

Those were probably 120mm mortars. They replaced the old Four-Deuce (4.2" or 107mm) many years ago.

Yeah, 120, you're right.
Balancing the nitogen rec oil system seemed to be the only downside for me.

Here is the future of 120 mm mortars.

Great System, looks very competative, but I have to ask, having maintained autoloaders and mortars, how difficult is it going to be to keep everything in syncronization?
One of the most difficult things to get Engineers to understand is some mud covered exhausted 19 year old has to be able to fix this on the fly in the field, day or night.

Pretty cool. I always harken back to the common denominator, a grunt (11C) in an environment that wouldn't be very permissive of armored vehicles (Afghanistan, Vietnam). That's when your traditional ground-mount platforms come into play. Other than the places that geography makes it unworkable, these modern mechanized shoot-and-scoot vehicles are the shiznit.

The US is producing 168,000 155's per year and there's only one plant in PA that makes them. Russia is producing 2 million per year.

Also worth noting US production of these artillery shells is dependent on materials that are not all sourced domestically.

US 155 production is up to 28,000 per month or 336,000 per year and is due to increase to 100,000 or 1.2 mil by 2025 and then there is the rest of NATO.

"We’re going to be at 100,000 per month in 2025. We were at 14,000 per month 6 or 8 months ago, we are now at 28,000 a month today," Bill LaPlante, the Pentagon’s weapons acquisition chief, said at a conference on Friday.

Watching the action in Ukraine, it seems like towed artillery or anything that can't pick up and move quickly is obsolete and nearly suicidal in combat against a near-peer army. Are there any exceptions to that? How fast can a towed piece go from a precise firing position to transport?

I have no idea, but...

Currently re-reading Red Phoenix, written in the 1980s. They talk about counter battery being pretty quick and based off radar telemetry of artillery shells.

I assume 40 years later its quicker. I would imagine 1-2 shots and move, but again, that's a SWAG on my part.
