Designed in 1942, which is before the point where the BattleTech timeline split from real life. That means it exists as-is in BattleTech. It's an amphibious vehicle that, were it put onto the battlefield, would be obliterated by something as simple as a Machine Gun (the weapon found on BattleMechs, not the generic class of weapons). When you see something like the Amphibious Chassis Modification having a minimum tech rating of C that does not mean you have to have technology that would be futuristic to what we have today. What it does mean is if you want to build an amphibious vehicle that can survive the rigors of combat in the BattleTech universe then you do need the greater level of technology.
What?
Whether the amphibious vehicle is meant for combat or not it's chassis still has to have a minimum tech level of C. That tech level isn't available during WWII. That time period is listed as Tech A.
If Combat vehicles so greatly outclass support versions, why does the Combat VTOL have a lower tech rating? Wouldn't a Tech C VTOL outclass a Tech B VTOL?
For other examples you have Environmental Sealing (seen on the M1A1 Abrams in 1985), STOL (seen on the Westland Lysander in 1936), and VSTOL (Yak-38 in 1971 - excluded experimental aircraft that date back to the 1950s). All Tech C, all predate their expected minimum tech rating, and all would be outclassed by their BattleTech counterparts. Bumping to Tech D you get Ultra-Light, a modern example of this would be the shift from the Audi V8's steel frame to the Audi A8 aluminum frame. Lighter, more expensive, purely an example of materials science improving existing tech. Bump it up again to E and you get omni. Bobcat Skid-Steer (http://www.bobcat.com/loaders/skidsteer/) offers seventy different attachments. That's omni technology found in 2011, according to your arguement shouldn't be available until the Star League comes around. But it is here, and like everything else listed above would get creamed if it somehow showed up on the BattleTech battlefield.
I'm away that there are many vehicles that are listed as Pre-space. I've pointed many of them out. But they can't be built because the technology isn't available. We even have autocannons Lasers and other high tech equipment like you said, but our reality isn't Battletech reality. You can't build a 20th century omni vehicle because omni technology didn't exist at the time. To say you can breaks the rules.
And not everything built now would be creamed by "modern" battletech equipment. They'd be greatly outclassed but they'd still be effective. Also some Battletech equipment has introduction dates of PS and they're still as effective.
However what is being missed is that once something of one tech level exist doesn't mean everything automaticly switchs over to that tech level. There are going to be some things of a higher tech level before a world has truley moved to that tech level. Because there must be a transition period
True, there will be an adjustment period but that means that the technology is improving or becoming more widespread. Internal combustion engines have been improving for centuries
http://en.wikipedia.org/wiki/History_of_the_internal_combustion_engine yet they're listed as Tech B (Late 20th Century) Why isn't there a Tech A Internal Combustion Engine?
And the tech intro dates tell you if the tech level is available. For example:
You want to build an actual WW2 submarine, requiring Tech B submersible chassis modifications and Tech B ICEs. Were those Tech B items available in 1941? Checking a BT sourcebook (like the House Kurita SB, which touches on WW2), yes. Clearly, those elements of Tech B were available in 1941. Proceed to build your 1941 submarine with Tech B equipment.
Except Tech B is classed as late 20th Century. Even if allowed as a "transition period" WWI submarines still could not be built.
No, but you are the one who is badly misunderstanding why eras are given with tech levels. I am one of the writers who was involved in setting the tech levels and assigning them to equipment, and I'm trying to explain tech levels.
Is there some way I could explain tech levels so you do not erroneously relate tech levels to an era like this...
Then as one of the writers why didn't you put the tech levels of items at the level in which they were available? If Internal Combustion Engines are available before WWI, why aren't they tech level A? If Amphibious Chassis are being tested during WWI, why aren't they tech level A? If the technology can support it, let it. If vehicles are going to be available, let them be available. If an item is prespace let it be able to be built with pre-space technology. That's 1950 or before. And please if a class of vehicle is going to be available, don't have different tech rating for combat and support.
You're correct, you can't have Tech A vehicles with combustion engines, but if you want to play WW2 then you can use Tech A, Tech B, and Tech C, since elements of all of those tech levels were present in WW2. Most WW2 (and WW1) combat vehicles and their supporting industry were Tech B, so feel free to build WW2 vehicles with Tech B combustion engines. Their introduction dates clearly show such Tech B items were available at the time.
I mean, you know that tech levels often overlap, right?
And WWI vehicles? How would I build them? What you're basically saying is to move Tech Level B back 50 years. That would bump Tech A back before 1900. But what about other items that were available then like VTOLs and Amphibious Chassis and Environmental Sealing. I know Battletech history doesn't have to follow ours exactly but shouldn't they also be tech B as well? How about Electric Vehicles? They used to be more popular in the mid 19th Century but they're rated Tech C.
http://en.wikipedia.org/wiki/Electric_car Shouldn't there be Tech Level A and B electric engines?
I am looking at page 357... it doesn't say that. It says that unless otherwise noted, all the bomb munitions can be carried by conventional fighters, ASFs, and aircraft properly equipped. The only note I see on 357 is the tag in the AAA missile detail box that said aerospace units... now, are you interpreting them as only aerospace fighters? In that case, all the air to air missiles can't be lifted by conventionals... all you need is the right number of hard points.
It's on page 358 in my book. I don't see where it says its only used by aerospace fighters though or can't cross into orbit.
