Myth...??? Yeah...a determined enemy used the road beside the base for taking off those migs .
if its a possibility , runway denial is nothing but a myth
specially when mig-29 can take off like this
To start, you need aircrafts DESIGNED for partially finished runways. The preferred phrase is 'improvised runway'. But even if the aircraft can use improvised runway, there is still a need to defend, maintain, and repair the normal runway system as much as possible.
Now, here is something for you to consider...
Aircraft load can, not always, be affected by improvised runway. The more 'improvised' the runway, you have two choices: Either you take longer for TO/L or you reduce your combat load to use the same length as the normal runway. The improvised runway do not have the same load rating, surface constant, traction value, and several other factors. You think am making this up?
Here is just ONE examples of many docs regarding runways...
Why did I used a US Army doc? Because the Army have a lot of experience in living/working with improvised runways. Use keyword 'soil' for example. You will see issues such as load rating, jet blasts because often the Army has to make runways for AF cargo jets. There is a section in there for C-130 and C-17 operations.
The following are standard design requirements for most airfield construction or restoration missions:
Design of drainage system structure.
Geometric design of RWY, TWYs, and hardstands (including overruns, blast areas, and turnarounds).
Selection of soils found in cuts and use of soil to improve subgrade.
Compaction or stabilization requirements of the subgrade.
Determination of type and thickness of the base and surface courses.
Selection of grade to minimize earthwork while still meeting specifications.
Design of access and service roads.
Design of ammunition and petroleum, oils, and lubricants (POL) storage areas, NAVAIDs; hardstands, maintenance and warm up aprons, corrosion control facilities, control towers, airfield lighting, and other facilities
See the highlighted: construction or restoration.
Restoration from what? Maybe the improvised runway was also damaged in the attack. Or maybe harsh weather washed off some surface soil. Or maybe freezing temperature made the improvised runway too slick to be used.
Table 4-1. Army airfield and heliport classes Class Definition (controlling aircraft weights reflect operational weight)
I Heliports/pads with aircraft 25,000 lbs. (11,340 kgs) or less. Controlling aircraft (UH-60)-16,300 lbs. (7,395 kgs).
II Heliports/pads with aircraft over 25,000 lbs. (11,340 kgs). Controlling aircraft (CH-47)-50,000 lbs. (22,680 kgs).
III Airfield with class A runways. Controlling aircraft (combination of C-23 aircraft-24,600 lbs. (11,200 kgs) and a CH-47 aircraft at 50,000 lbs. (22,680 kgs). Class A runways are primarily used for small aircraft (C-12 and C-23).
IV Airfields w/class B runways. The controlling aircraft is a C-130 aircraft at 155,000 lbs. (70,310 kgs) operational weight or a C-17 aircraft at 580,000 lbs. (263,100 kgs) operational weight. Class B runways are primarily used for high performance and large heavy aircraft (C-130, C-17, and C-141).
V Heliports/pads supporting Army assault training missions. Controlling aircraft (CH-47)-50,000 lbs. (22,680 kgs).
VI Assault landing zones for operations supporting Army training missions that have semi-prepared or paved landing surfaces. Controlling aircraft (C-130-155,000 lbs. [70,310 kgs] or C-17-580,000 lbs. [263,100 kgs]). Legend: lbs= pounds, kgs= kilograms
Do you see those tonnage ratings for different aircrafts? Even smaller and lighters fighters, like my F-16, are affected.5-36. Weather, terrain, RWY conditions, amount of available equipment and remaining fuel, and crash location are some factors that govern placing equipment at an aircraft's crash operation. Prefire plans can only cover general placement procedures and should allow for flexibility, based on the situation. Other factors to consider include—
Aircraft's landing speed.
Wind direction and speed.
Aircraft's stopping distance.
Do you see the highlighted above?
The literature on runways and airfields are enormous, even if dealing with austere airfields and improvised runways. Everything in that Army doc are applicable to the AF in either making improvised runways to supplement the main system, or in deploying to austere airfields with improvised runways. I may have no choice but to sortie with reduced loads because the improvised runway cannot handle the full load.
People like you who have no experience looks at a picture and thinks they know everything about the subject. Runway denial is a myth? I hope the entire Iranian military leadership is filled with people like you.
