Running out of runway.



Hat tip to Eric Palmer!

 Eight-thousand feet.

That is the minimum amount of runway required to safely operate the conventional take-off and landing (CTOL) version of the F-35, the F-35A.  For training purposes it is preferable for the newbie F-35 pilot to have up to 10,000 feet to allow for a margin of error.  This is according to RAAF documents, found here (warning:  PDF download).

For those not keeping score, the CTOL F-35A was (is?) the planned replacements for the RCAF's aging CF-18s.  Being a carrier-capable aircraft, the CF-18 has little problem operating out of shorter runways.  Strengthened landing gear, low stall speed, and an arrestor hook make for snappy take-offs and landings.  The F-35A lacks these benefits, as they are not required to operate out of large USAF airbases with more than enough runway to go around.

For Canada, things are a little different.



Canada's current fleet of CF-18s are operated out of two airbases, CFB Cold Lake, Alberta and CFB Bagotville, Quebec.  From these two bases, CF-18s are often rotated to CFB Comox (BC), CFB Goose Bay (NL), CFB Gander (NL), and CFB Greenwood (NS).  CF-18s also often find themselves in CFB Trenton (ON).  All of these bases meet the 8,000 foot requirement for the F-35, some of them, just barely.

Here is a list of these bases along with the length of their longest runway, in feet.


  • CFB Cold Lake:  12,600
  • CFB Bagotville:  10,000

  • CFB Comox:  10,000
  • CFB Goose Bay:  11,051
  • CFB Gander:  10,200
  • CFB Greenwood:  8,000 (the minimum)

  • CFB Trenton:  10,000


Things get hazier when we look at Canada's Forward Operating Locations (FOL) up north.  These FOLs allow the fighters to operate in Canada's northernmost territory.  These locations share a runway with a civilian airport and simply do not have the resources of a full military base.  These runways are built with small, commuter aircraft in mind, not stealth fighters.


  • FOL Yellowknife:  7,503
  • FOL Inuvik:  6,001
  • FOL Rankin Inlet:  6,000 
  • FOL Iqalut:  8,605


Notice that Iqalut is the only base the meets the minimum requirement.


"A detachable pod that deploys a chute directly behind the jet nozzle in order to keep the multi-million dollar fighter from careening off the runway and into the landscape?  What could possibly go wrong?"

Of course, Lockheed Martin is working on a drag chute to help reduce landing distance, these of course, cost extra.  They are also rather unique in the fact that they need to be constructed out of kevlar instead of the usual nylon.   This is due to the chute's position directly behind the F-35's engine nozzle.

Like much else attached to the F-35, the drag chute "pod" still needs to undergo testing before it is cleared for service.

By the way, here are some distances needed by other fighters at Maximum Takeoff Weight (MTOW):


  • Boeing F/A-18E/F Super Hornet:  3,680ft (Maximum Landing Weight)
  • Eurofighter Typhoon:  2,300ft
  • Dassault Rafale:  1,475ft
  • Saab Gripen NG:  <2,000ft


Of the above, the Super Hornet, Rafale, and Gripen are all capable of "rough field" conditions.  Both the Super Hornet and Rafale (M) can use tail hooks.  The Typhoon already has a drag chute installed. The Gripen simply does not need any additional stopping aids.

So what shall it be?

  1. Retrofit a few runways?
  2. Install a (so far untested) drag chute?
  3. Procure an aircraft that manages just fine as is?
Given the extra costs associated with the first two choices, this really is not much of a choice at all.

THE REAL REASON THE GRIPEN LOST...

Image
  For those of you wondering how Saab lost the FFCP competition, new information has come to light... According inside sources, the initial scoring of the two fighters was incredibly close.  The F-35 did indeed win the "Capability" category (worth up to 60%) while the Gripen E ended up being ahead on both price (worth 20%) and industrial offsets (worth the remaining 20%).   According to my source April Furst, who is currently serving an internship in the House of Commons.  The ultimate decision was made rather hastily while the final scores were being tallied up.   "Due to COVID restrictions and renovations, the FFCP committee were forced to convene in a remote office located in the basement of the Parliament building.  You could tell it wasn't used very often.  Lots of cobwebs, and the whole place smelled musty and moldy.   "The committee members were doing their thing, going down each individual line of the respective offers.  It was actually pretty close, by

FINAL THOUGHTS

  So…. Now what? The process is still far from over but what is left is mostly mundane and bureaucratic.  Stuff like finalizing costs, delivery dates, etc. Hopefully, Canada can now focus it procurement efforts on  revitalizing the rest of the Canadian Armed Forces.  With fighters and frigates out of the way; it’s high time we look into replacing our submarines, MRTTs, and other.  Recent lessons from the war in Ukraine has also made it clear that UCAVs are the future of warfare.  Canada best catch up. Was all this for nothing?  No.  I do not believe so.  Even though Canada is still choosing the F-35, it is doing so in a much more rational way.  We have taken the time to evaluate our needs.  Taken a clear look at the options.  We have arrived at a decision removed from political whim.  Ultimately, Canada is getting a lot more aircraft than initially planned.  We are also getting later build F-35s.  Now, more of the kinks are out.  These newer aircraft should be both more reliable and mo

Fighter Jet Fight Club: Gripen NG vs. Super Hornet!

Image
I will be honest...  I have been dreading this installment of Fighter Jet Fight Club.  I tend to root for the underdog in any competition, but what happens when underdogs have to compete against each other?  Both of these aircraft have a 0-2 record for FJFC, yet both are clearly crowd favorites in the comment section. Our contestants today are two of the biggest value propositions in the fighter world today.  Both are "modernized" versions of aircraft that have been flying since the 80s.  Neither make promises of being the most dominant force in the skies, but they do promise a "90%" solution at "50%" of the cost.  Most importantly, both aircraft are "tried and true" designs that have provided years of faithful service.  Despite this, they are often overlooked in favor of newer, flashier aircraft like the F-35 Lightning II. Which aircraft will see redemption here today? Just remember the rules . Air-to-Ground: Infiltration/Pe
