Temple Airstrike Challenge

2gzAaXP.png

Objective

The Kerbal Air Force has ordered a strike on the desert temple to the West of KSC. The temple lies within the airspace of a rival space agency, so speed and stealth will be paramount to the success of the mission. Design an attack aircraft to complete the mission profile as outlined below. Points will be awarded based on successful completion of the mission.

Mission Profile

-          Take off from the KSC runway.

-          Cruise to the target, the desert temple West of KSC.

-          Attack the temple by deploying at least one weapon from the aircraft.

-          Return to base and land at the KSC runway.

Rules

-          Any mods / part clipping / ect may be used, so long as they are not overpowered or designed to cheat physics. Note if you are using FAR as I'll list that on the leaderboard.

-          The aircraft may not use space grade parts (rockets, RCS, reaction wheels).

-          The aircraft may be manned or un-manned.

-          A “weapon” is herein defined as any stock or mod part or assembly which is launched from the aircraft. BD armory bombs or missiles are allowed, but rounds fired from guns or cannons may not be used to complete the achievements. Weapons may be guided or un-guided and may use rocket engines.

-          A maximum altitude limit of 25km must be observed for the duration of the mission.

Points

-          Direct Hit: The following points are awarded for scoring a direct hit on the large center temple. EDIT: Multiple hits do not earn additional points, 100 is the maximum for this achievement.

                              +100 pts if a direct hit on the temple with the 1st weapon that is fired.

                              +75 pts if a direct hit on the temple with the 2nd weapon that is fired.

                              +50 pts if a direct hit on the temple with the 3rd weapon that is fired.

                              +25 pts if a direct hit on the temple with the 4th weapon that is fired.

                             +0 pts if no direct hits are scored or if it takes more than 4 shots to score a hit.

-          Collateral Damage: The scientists at KSC urge you to try and preserve the other scientific artifacts in the area. -10 pts if any weapon impacts one of the 5 smaller temples surrounding the large center temple.

-.          Unguided Weapons: +5 pts if weapon is not guided/controlled.

-          Attack Altitude: Enemy air defenses will have an easier time shooting you down at low altitudes. +1 pt for every 1km of altitude above which the weapon is deployed. (Ex. I fired my missile from ~5600m = 5 points). The weapon must hit the temple is order to earn these points.

-          Mission time: -1 pt per minute of elapsed mission time from takeoff to touchdown.

-          External Stores: -5 pts for each weapon stored externally. (Weapons do not need to be in an actual “cargo bay” part to count as internal, but they must be shielded from the airflow).

-          Radar Cross Section: Small aircraft are more difficult to detect. The aircraft’s radar cross section will be estimated using the size reported in the Engineer’s Report in the SPH. Remember to retract the landing gear as they add height!

                                                # pts = -0.5 * ( Height + Length + Width )

-          Heat Signature: Engines with high heat signatures will degrade the aircraft’s stealth performance. -10 pts if afterburners (Panther “wet” mode) or Whiplash engines are used during the strike at any point during the flight. (If using mod engines, use your best judgement on this penalty).

-          Cost Savings: Developing new technology is expensive. +10 pts if only stock parts are used.

 

Here's my entry: http://imgur.com/gallery/aCOlu41

(I'm using FAR fyi)

Direct Hit 100
Collateral Damage 0
Attack Altitude 5
Mission Time -43
External Stores 0
Radar Cross Section -13.5
Heat Signature -10
Cost Savings 10
   
TOTAL 48.6

 

Please calculate your own scores and I'll add them to the leaderboard.

Horrible thing is I think I have a strike aircraft that will be able to do this... I am also sure my oldest design can do this...  I still use a 4 year old fighter I designed back in the day with very few actual modifications to the original plans for most of my scientific work on Kerbin....  Last mission I strapped 3 drop tanks to it and a science pod to complete the mission.   So I will play with this mission when I get home.  

One question though, I run FAR + AJE mod... so none of my engines are stock, they all run like real jet engines, so they use more fuel and have separate wet and dry modes based on the throttle position.  How would I even score those?

AJE does afterburners when greater than 60% throttle right? So I'd say if you use more than that amount of throttle during the flight, subtract the 10 points.

ETFtzdd_SW4.jpgI bombed that temple with my carrier based strike fighter. Weapons: 2x cruise missiles, 2x air-to-air. Take off and recovery from aircraft carrier, standing ~ 20 kilometers to the East of KSC

So I am kind of up in the air over which aircraft to use for this challenge. 

I have my new strike aircraft... the FB-160... which has fuel to spare for this trip and is more than capable of destroying the target and everything around it need be. 

COlAeFr.png

That is actually 2 rotary racks, the first one just happened to have 100unit drop tanks on them for range testing and 4 Hellfire missiles.  But that craft super cruises at mach 1.2 at 97% throttle no afterburner at 7km alt.  It is capable of hauling 16k pounds of bombs internally.

Or I go with my tried and true... new leading fighter.. the F-152B...

voxbWxN.png

Not at all stealthy, but has great internal fuel range and is actually the easiest to fly and land.... thanks to a drogue landing chute.

 

Or do I use the oldest aircraft in my inventory... the F-119CA Akula....  It has the range of a gnat without drop tanks...

kDjqR9Y.png

But it can super cruise at mach 3!!!!!  at 99% throttle no afterburner.  Or at mach 1.5 at 50% throttle.  But has a whopping 15min of flight time on internal fuel. 

If I can I may do 3 aircraft tomorrow when I get home and get a chance.

Quick question about the mission.   You state the release height of the weapon is what is counted... can you fly higher than that till you get to the target area? 

 

And how would BD Armory weapons be scored?  Because I can hit the target with a Maverick missile from 6KM out using the laser designator pod but the missile will travel through the structure because.. well KSP...

Yes, just not over 25km altitude.

That's fine, just count it as a guided weapon.

Ok just checking.  I figured these would be counted as guided weapons...

JDAM 1000lb bomb, TOW Missile, Hellfire, Maverick, RBS-15 Cruise Missile, AGM-165 Cruise Missile and a few other AGM I am probably forgetting.  

I dont plan on using guided weapons though.  Probably using 1k snake-eye bombs or standard dumb bombs.   Considering I can put a light load on the F-119CA Akula with 4 drop tanks and get it across that distance... and hope it has enough fuel for landing.

 

AJE makes a HUGE difference in your fuel use.

...What if you fired a ballistic rocket from KSC, with no guidance V2 style, and hit it?  Different contest I suppose.

If you want ICBM Chunkin', check out this challenge: ;) 

Anyway, on-topic, I'm working on designing some aircraft (mainly VTOL's) and this looks like fun, so once I have a working long range jet, maybe I'll try it out.

And now for the F-152B

Take off and climb out.

HbjHdwg.png

Missile is on its way to target.

AXk4amp.png

SPLASH!!! 

F8f9qyh.png

Jettisoned second missile and was already turned home.

fsVsKp2.png

Touchdown and drag chute deployed for landing. (yes I use drogues for my landings because brakes are "iffy")

HrMjz9O.pngfxzcAvN.png

 

Total elapsed time 45min

 

So score would be...
