Have you seen the photos of the airships hangers at either Moffet Naval Air Station in California or at Lakehurst, New Jersey? For that matter, have you seen any photos of the hangers used by the Zeppelins in World War 1? Also, have you ever seen photos of the hangers used at US Commercial airports in the 1930s? They were not "wood construction overlaid with canvas".
I have more than a passing familiarity with the Airship hangers of the Hoo peninsula, Those were of steel construction clad in corrugated iron and constructed using prefabricated parts made by Vickers Ltd.
You've selectively quoted me. what I said was "Most hangers of the 1930s where wood construction overlaid with canvas, wood a or corrugated iron.". You'll note in the quoted passage on Hangers from p.648 lists both permanent and temporary structures. Have you ever seen the canvas hangers used by the RAF in the Middle East during the 30s, have you ever seen the USN Hangers 2 and 3 at Moffet Airfield? By the way there is a generally accepted differentiation between
Hangar and
Airship Hanger when dealing with them in an architectural context due to
size and
purpose.
But these are circular arguments. I'm interested in solutions to problems. However, I don't see a problem with the quoted descriptions in regard to Tech Level.
Hangar
TL 8, Size 7, Cr 20,000
An open structure, made from standard construction materials, designed to shelter aircraft (sometimes very large) with plenty of access space to perform maintenance.
Temporary Hangars, Size 6, Cr 5,000, are designed to hold one aircraft with minimal space for maintenance. Typically 150m x 75m x 20m.
Aside from the super-controlled hanger environment needed for the Stealth aircraft, you are not going to have a whole lot of different between hangers from the 1930s and hangers today. Have you visited an airbase or large airport lately? Although if you are in Ireland, scratch the airbase. Civilian construction rules and building codes change very slowly if at all.
I feel that was slightly snarky, as yes I have visited the hangers at the Irish Aer Corps Casement Aerodrome. The hangers there have a range of construction dates from the 30s to the 90s. Ninety-three years experience in aircraft hangaring not counting the previous RFC, RAF and RNAS structures on that and other sites.
If you want an education in large hangar type structures where the aim is to create a large open structure suitable to conduct maintainance or construction I suggest you look at a TL3 example; the Covered Slips of the Royal Dockyards of the UK such as Chatham. Slip No. 3 is the earliest still surviving and was constructed of wood and tarred paper.
I take it that you define anything that is handmade as Early or Prototype. How do you handle ships, where they are either custom-built or built in very small numbers to the same design? For that matter, how do you deal with cars such as the Lamborghini, which are basically hand built? As for aircraft, Boeing might build 50 to 60 passengers jets a year. Does that qualify as mass-production? The US built a total of 21 B-2 Stealth Bombers. That is not mass-production, and every one of them was hand-built. No assembly line.
You take it wrong. I assume that Early or Prototype items are bespoke, requiring ether manual construction or the input of a craftsperson.
Lamborgini's would be TL5-9 construction Cars with the Luxury modifier in VehicleMaker. They would not benefit from any price reductions associated with mass production and would probably be classed as Scarce to Rare for Supply and demand determinations.
Boeing builds up to 700 airliners a year (in what I think of as a TL8 climate controlled hanger environment. See
this National Geographic documentary for visuals). I'd class it as mass production not on the basis of numbers but on the basis that each example within each model of aircraft is basically identical and produced using a production line technique utilizing jigs and prefabricated parts to ensure that each example rolling off the production line can be supported by a common maintenance and spares system. There is no requirement for a craftsperson to use trade skills built up over years of apprenticeship to work on any given example of a particular model. A technician with a toolkit and the proper learned skills and knoweledges in Traveller terms can work on any given example of a model in a fleet.
The B-2 could be constructed as a Winged Bomber with the application of a StealthMask from ACS. Final TL would depend either on the required performance if you go the Fillform method or could be set at TL8 or Early TL9
Do you understand that to increase sonar range, you go to lower frequencies? Lower frequencies mean much larger sonar transducers. The bow-mounted low frequency transducers used now take up the entire bow of a submarine, and may be 30 or more feet in diameter at the bow of an ASW ship. I understand that no Traveller design sequence plugs the size of a radar antenna into the equation for size. I have worked with deep-sea sidescan sonars which can also give some bottom penetration depending on the bottom material, but they use high frequencies that severely limit range. If you want a basic course and overview of sonar systems, I would suggest Norman Friedman's
US Naval Weapon Systems as probably the best unclassified source. He worked with the unclassified US Navy technical and training manuals for that. The same with his book on Naval Radar. Data on World War 2 radar can be found on the Internet at Hyperwar and in the US Army Signal Corps histories from World War 2. Jane's Weapon systems and Air Defense Systems are also good sources for current systems. However, for radar, if you want long-range and high resolution, you go to very large antenna arrays. To get an idea of how large they are, check on the US Safeguard system radar at
https://en.wikipedia.org/wiki/Safeguard_Program. You are talking about antennas the size of the Great Pyramid.
If the adaptation of DeepRadar as a Sonar substitute in the rules doesn't suit due to the volume requirement being too low, can I invite you to submit a Sonar sensor written in the T5 Sensor format found on p.299.
