AIRSHIPS

Classification

Military Airships are divided into 6 types, sorted for size and structure.

Type 0: 10 000m³ (nonrigid), 1 tons military payload, speed 30kts:  $0.10
Type 1: 20 000m³, 4 tons military payload, speed 40 kts:  $0.20
Type 2: 40 000m³, 9 tons military payload, speed 50 kts:  $0.40
Type 3: 70 000m³, 16 tons military payload, speed 60 kts:  $0.70
Type 4: 130 000m³, 31 tons military payload, speed 65 kts:  $1.30
Type 5: 210 000m², 60 tons military payload, speed 70 kts:  $2.10

Building and maintaining airships

Building time is six months.  Airships are financed from the military budget.

Construction, maintenance and safe storage happens in hangars. Landed airships are vulnerable to the weather, so they have to be stored in these huge structures if they are not in use.  You must have one hangar for every two airships.

If less hangars are constructed, 1 or more airships, according to the mathematic ratio will be subject to a wear and tear ratio equal to the ratio applicable to warships. With the following provision:  Airships below 50% can't fly.

Operations

The maximum endurance of an airship is 2hr for every 1000m3 of volume at a cruising speed of 40kts.

Maximum payload can be delivered up to 1/4th of the range.  Half the payload can be delivered to 1/2th the range.  The payload that can be delivered to the maximum  distance is effectively zero.  Between distances, payload scales linearly.

Example:  A 40,000m³ airship has a payload of 9 t. Its endurance is 80 hr. It can take 4.5 t for a 40 hr flight, or 2.25 t payload to a 60 hr flight.

An airship requires 1 hour maintenance for each hour spent in air.  This costs nothing, but functions as a limitation on operational tempo.

Upkeep

Maintenance requirements for airships are high, and they need frequent overhauls.  They are treated as land units - 12.5%/25% peacetime/mobilized upkeep per six months.
Airships cannot be put in reserve.

Design Life

An airship has a life of six years in peacetime conditions.  Heavy/wartime usage puts much higher demand on the airframe, and degrades the airship twice as fast - each six months counts as a full peacetime year.

Damage

100-86%:   Normal working aspects in airships. Doesn't affect any of the capabilities, unless it is visual. This is payed for in the upkeep

80-66%:  Range/speed/lifting capacity is reduced due leaks in the gasbags, and wasted ballast or fuel.  To repair this, the airship needs an input of 10% of the basic cost.

65-50%:  Barely airworthy, capacity lost in range/speed/lift is such that the nearest landing spot under controlled circumstances is needed.  To repair this, 25% of the original cost must be spent.

50-35%:  A controlled hard landing is the only option, but further damage can be avoided.  If the airship survives this crash, a reconstruction is possible at 50% cost, if the large lumbering hulk can be put into a hangar.

34% or less:  The airship crashes and is destroyed.

Hangar Cost

Type 0:  $2
Type 1:  $3
Type 2:  $4
Type 3:  $5
Type 4:  $6
Type 5:  $7

AIRCRAFT

1902:  Primitive flying machines (storyline stuff only)

AIRCRAFT: No cost, just sane numbers (maybe 100 or so max)
AIRFIELDS: No cost, but you can't use them for anything past this level
 
1906:  Historical 1910 aircrafts

AIRCRAFT: $0.10 for 100 single-engine aircraft (not really any 'types' at this level)
AIRFIELDS: $0.50 per airfield; basically, just a flattened piece of land

1910: historical 1914 aircrafts

AIRCRAFT: $0.10 for 100 single-engine aircraft
                 $0.20 for 50 multi-engine aircraft (with historical bomb load)
AIRFIELDS: $1.00 per airfield; includes hangers, fuel tanks, support personnel

1913:  historical 1916 aircrafts

AIRCRAFT: $0.20 for 100 single-engine aircraft (fighter or bomber with historic loads)
                $0.30 for 50 multi-engine aircraft (with historical bomb load)
                $0.40 for 25 long-range bombers (with historical bomb load)
AIRFIELDS: $1.50/.5BP per airfield; includes hangers, fuel tanks, support personnel

1917: historical 1918 aircrafts

AIRCRAFT: $0.30 for 100 single-engine aircraft (fighter or bomber with historic loads)
                $0.40for 50 multi-engine aircraft (with historical bomb load)
                $0.50 for 25 long-range bombers (with historical bomb load)
AIRFIELDS: $2.00/1BP per airfield; includes hangers, fuel tanks, support personnel

1921: historical 1922 aircrafts

AIRCRAFT: $0.40 for 100 single-engine aircraft (fighter or bomber with historic loads)
                $0.50 for 50 multi-engine aircraft (with historical bomb load)
                $0.60 for 25 long-range bombers (with historical bomb load)
AIRFIELDS: $2.50/1.5BP per airfield; includes hangers, fuel tanks, support personnel

1928: historical 1930 aircrafts

AIRCRAFT: $0.50 for 100 single-engine aircraft (fighter or bomber with historic loads)
                $0.60 for 50 multi-engine aircraft (with historical bomb load)
                $0.70 for 25 early long-range bombers (with historical bomb load)
AIRFIELDS: $2.50/2BP per airfield; includes hangers, fuel tanks, support personnel

Construction and Maintenance

A unit of aircraft takes six months to manufacture.  Upon completion, they are immediately available for use.

Like airships, a group of aircraft of this era are delicate and do not last long.  They are effective for six years.  Maintenance costs are 12.5% per half-year when active, and 25% per half-year when mobilized.

Aircraft can not be upgraded or modernized.

Airstrips require one month per $0.50 cost to construct.  Upon completion, they are immediately available for use.

Like ports, there is no maintenance cost associated with airstrips.  They may be upgraded to later/larger airstrips by paying the difference in cost between original and new configurations.  Airstrips can, in theory, be used indefinitely, so long as they've been kept up to the standards required of the aircraft using them.
