Dates and Times

Players should register for this Aces High scenario to play in it so that they can get mission orders, although walkons are allowed to show up in the Special Events II Arena on game day to see if there are any open positions to fill. This scenario will be a four-frame event (four battles) with one practice (or "beta") frame. The practice frame is on October 25, 2008. Frames 1-4 are on November 1, 8, 15, and 22, 2008. Show-Up Time is 3 pm US Eastern Time. (For how that translates to your time, here is a time converter.) All frames run in the Special Events II arena. (If there are two Special Events II's, go into the one that shows a large number of people in it or that has a ping number.)

Note: Daylight saving time in the US ends on November 2, 2008. If your time zone doesn't have daylight saving time or has it end on a different date, please be aware that Show-Up Time of this scenario might change for you during as a result of the US going off of daylight saving time.

Important: Please show up on or before Show-Up Time to play. The arena will be closed to admittance at Show-Up Time. If you are disconnected and can't get back in, you can private message the CM (Newman) from the Main Arena by typing ".p newman let me in" into your radio text buffer. Takeoff time will be about 30 minutes after Show-Up Time, subject to the CM's discretion, to allow for organization and briefing.

This is a 4-part scenario played across 4 frames. The frame ends approximately at Show-Up Time + 3.25 hours. The following table gives various time points in the frame.

It is July, 1940, and the fate of a nation is about to be decided.

Hitler has just given the order to begin preparation for Operation Sealion -- the invasion of Britain. France has fallen, the United States has not yet joined the war, and the Soviet Union is still Germany's ally. Britain stands alone.

The first order of battle is for the Luftwaffe to pave the way by destroying the Royal Air Force and pounding British infrastructure and cities. The Luftwaffe is mighty and skilled. The RAF is outnumbered, but it has the world's most advanced radar system -- and something just as important: an indestructible will to repel the Luftwaffe, no matter what the personal cost.

The Battle of Britain scenario will pit the RAF in its Hurricane Mk I's and Spitfire Mk I's against the Luftwaffe in its Bf 109E's, Bf 110C's, Ju 87's, and Ju 88's. The Luftwaffe will work to destroy all airfields, ports, and ships in the southeast of Britain. The RAF will do whatever it can to stop them.

The fate of Britain hangs in the balance.

Further Introductory Details

The Battle for France had been lost. The Battle for Britain had begun.

Whilst Britain girds its self against an expected invasion, Goering has finally convinced Hitler to allow him to commit his Luftwaffe to eliminating the RAF from the skies of South East England.

The broad objective is to simulate some of the strategic, tactical, geographic and logistic circumstances of the conflict between the LW and RAF fighter command during the months of August and September 1940.

The LW objective is to inflict sufficient damage to the RAF to gain total air superiority over the Strait of Dover , Kent, Sussex and the Solent approaches as well as disabling local ports for use by the Royal Navy.

Given this the initiative is with the LW and the win/lose definition will hinge on whether the LW has achieved its objectives at the end of the final frame. Points will not play a deciding roll in this scenario.

Geography (Terrain)

The terrain will be based on a near full sized European landscape. Fields, ports, townscapes, radar sites and shipping will be changed and added to recreate Southern England and Northern France/ Belgium. This scenario uses the "bob04" terrain.

As the "battle" and its objectives hinge around Southern England then these have been paid particular attention. Looking at a map of Southern England at the time we will attempt to recreate the following.

All other normal "Strat" objects removed out of the area of battle.

The RAF divided bases and terrain into "Groups" and "Sectors" (these Sectors being different than what we normally mean in Aces High by the word "sector"). The groups are 10 Group, 11 Group, and 12 Group, and are shown on the map in blue lines. Groups were divided up into Sectors. The Sectors are A (Tangmere Sector), B (Kenley Sector), C (Biggin Hill Sector), D, E (North Weald Sector), F (Debden Sector), G, J, K, W, Y, Z, and London (Hornchurch Sector). Radar-control Sectors are shown on the map in purple lines.

The most important aspect of the fields locations for the LW is that they simulate the distance and directions of approach that the LW experienced in 1940. We can leave much of this to the skill of the terrain modifier however a rough guide would be fair smattering of fields from St Malo thru Cherbourg, Caen, le Havre, Amiens, Bologne, Calais and onto Gent and Antwerp.

Detailed Victory Conditions

As stated above the LW must pave the way for a German invasion of SE England. (Operation Sea Lion). In essence the main LW strategic plank was the destruction of the RAF on the ground plus the neutralisation of the Royal Navy in the area of the English Channel (la Manche) known as the Strait of Dover (Pas de Calais).

We will define this in the following way.

Objectives for the end of Frame 4:

1) Deny the RAF use of all its airfields South of the Thames and east of the Solent.

This is achieved by the destruction of fighter hangers to a point where by fighters may no longer take of from these fields. Forcing the RAF commander to use other fields to house his squadrons. This will include those fields which were initially used by Coastal Command which falls within this area. They are all within 11 group sections Tangmere, Kenley, Biggen Hill and parts of Hornchurch that's are south of the Thames. (Croyden is considered to be within Kenley section.) Specifically, the following are the airfields that must be disabled: a20, a113, a124, a18, a19, a17, a23, a9, a8, a7, a10, a11, a12, a13, a14, a15, and a16.

2) Neutralisation of the Royal Navy local to the Strait of Dover.

2a) The Ports and Docks

All ports listed above are Neutralised by taking out the Vehicle Hanger, and 50% of the ports associated city infrastructure. These objectives include the South coast Ports which are based on or to the East of the Solent. (Therefore excluding the Portland & Poole facilities.) Specifically, the following ports must be disabled: p107, p95, p105, and p106.

2b)The Flotillas

The cruisers in two of the three of the Flotillas must be destroyed.

The German Wehrmacht will not be ready to launch Sea Lion prior to the end of Frame 4. Hence it is critical that the conditions are met at this point in time as achieving them prematurely will be to no avail if they cannot be sustained.

Arena set up details and special CM factoring

Terrain. bob04.res

Wind. 0 mph at 0-4000 ft. 5 mph from 4000 ft. to mid altitudes and 10 mph at higher altitudes. Winds will be from the S, SW, or W. Note that bomber pilots need to be aware of the effect of wind. Bomber pilots should consult the wind settings prior to initial mission in each frame. Winds will not be changed within a frame but might vary frame to frame. Wind settings will be announced prior to each frame.

Clouds. Partly cloudy as used in the practice frame (patchy clouds at various altitudes from sea level on up; thin, transparent layer at very high altitude, 40k or higher).

Icons. Short range (.icon 1).

Flotillas. The flotillas will be given separate courses between Portland (p109) and the North Foreland (v118) by the CM's. These may cross but flotillas will not escort each other.

Object Name



Bunk Radar 1.5 Radar takes 1500 lbs to destroy.

All other settings are the default settings listed here: http://ahevents.org/images/stories/scenarios_images/defaultSettingDocument/defaultArenaSettings.html

Radar and early warning…. Presently the only AH radar which is influenced by the destruction of radar objects is dot radar. All RAF radar stations will be designated to a third country. This radar will only be visible by a team of third country sector controllers who will guide the RAF squadrons to the target over private text and radio channels. No other radar will exist either as sector bar or dot indication. As the radar stations are destroyed so will the local dot radar capability.

British observer corps is to simulated by the use of the flashing "field under attack". The range will be set to the visual dot range of bombers of approximately 7 miles. This function will always remain in effect regardless of field/port/base status.

Radar objects will only be repaired after 1 further frame.

Fighter hangers will only be repaired after 2 further frames.

Flotillas cannot be repaired.

Ports and Docks, once neutralised, will remain neutralized.

Player should note that all other objects, guns, fuel, ammo, barracks and town/city objects, etc., and VH's at ports that have not been neutralized will be repaired prior to a subsequent frame. Further that "disabled" fields will still be available for emergency landing and refuelling/rearming during a frame.

The fuel multiplier will be chosen to give a Bf 109E approx 15 minutes flying time over London based on a climb to alt (18K) over Calais and straight ingress and egress losing alt over the Straits of Dover to land in the Calais/ Bologne area. Specifically, calculated by:

  • Get onto runway at a46 in a Bf 109E with 100% fuel and fuel burn-rate multiplier set to 1.0. Note fuel load in gallons (G_i).
  • Take off at full throttle and climb at full throttle and autoclimb to 18k, doing a racetrack pattern with straight legs and minimal turns (for maximum climb rate), and timing it so that you reach 18k about as you cross over a46.
  • Depart over a46 and head straight to RAF HQ.
  • At HQ, maneuver around for 15 minutes, including dives to 5k and climbs back to 18k, timing it so that you reach the end of 15 minutes at 18k over HQ.
  • Depart over RAF HQ straight for a46.
  • Once over water, start a 4000-10,000 fpm descent so that you reach 0-1000 ft when over a46.
  • When crossing directly over a46, note the fuel left in gallons (G_f).
  • Calculate fuel burn-rate multiplier to be used in the scenario as G_i/(G_i - G_f).

All other fuel endurances will be based upon this. The RAF will have the same fuel burn multiplier as the LW.

RAF Order of Battle

The RAF may have up to 6 active third country sector controllers during any one frame. These six sector-controller positions will be recruited by the RAF and will be in addition to the 84 pilot positions available to the RAF (6 per squadron, 14 squadrons).

A typical RAF squadron will consist of 6 pilots (being half the historical strength of an RAF squadron).

Total RAF squadrons will be 14 made up of 9 Hurricane MkI squadrons and 5 Spitfire Mk I squadrons.

For Frame 1 the following squadrons should be placed historically.

A Jagdgeschwader Gruppen will have 8 Pilots (each flying bf109E).

A Kampfgeschwader Gruppen will have 5 Pilots (each flying 3x Ju88).

A Zerstorergeshwader Gruppen will have 8 Pilots (each flying Me110C).

A Erprobungsgruppe will have 8 Pilots (each flying Me110C or bf109E).

The LW will have 9x */JG gruppen, 2x */ZG gruppen, 1x */EG gruppen and 7x */KG gruppen. Thus the LW has up to 131 pilots positions available (9x8 + 2x8 + 1x8 + 7x5).

Additional Rules

After T=0, pilots may go to tower only (1) upon landing at their assigned base or (2) upon being picked up by a rescue vehicle as witnessed by a CM. Pilots may refuel and rearm at fields other than their base fields. If you land at a base other than your assigned base and go to tower, you will be considered lost (the same as being shot down). If you ditch or bail somewhere and go to tower without are rescue vehicle picking you up and being witnessed by a CM, you will be considered lost. If you have a damaged plane, make it to a field (but not your assigned base), and are too damaged to refuel and get to your assigned base, ask for a rescue to get to your assigned base -- do not just go to tower, as you will be considered lost.


1) May not carry bombs.

2) 11 group may only launch (scramble) to known incoming LW sited via radar, the observer corps or scouts.

3) 10 group may only launch (scramble) when main elements of 11 group have launched.

4) One (only) squadron in each group may be allocated scout duties prior to scramble.

5) There are no limitations re scout range other than fuel limitations.

6) Aircraft may refuel and re arm at any available field.

7) There are no altitude limits.

8) Emergency Relocation. If a squadron's base is disabled (all FH's destroyed) during a frame, the RAF CO may assign that squadron a new base. The new base must if at all possible be in the same Group the previous base was in. The new base is not restricted to be only from among the list of bases in the table in "RAF Order of Battle" -- it can be any base within the Group as judged by the map of the terrain, given above.

9) Between-Frame Relocation. Squadron base fields can be moved around (between Frames, after Frame 1) within groups but not across groups. A squadron can be moved to a new base, but that new base must be in the same Group area and must be one of the bases listed in the table in "RAF Order of Battle". The squadron can be moved to a small airfield only if that small airfield will then have two or fewer squadrons based there and to a large airfield only if that large airfield will then have four or fewer squadrons based there. Note that this "bunching up" restriction and the restriction on the new base being from among the bases listed in the table is for Between-Frame Relocation -- these two restrictions are not applied to Emergency Relocation.

10) Downed (lost) RAF pilots will able to take up ground gunner and observation positions.

11) Rescued RAF pilots can re up after T = 60 minutes (see rescue below).

12) Damaged aircraft returning to their home/origin field may under go repair and re launch. Pilots returning to tower at other fields (unless under rescue rules) will not be able to re launch.

13) Note that radar stations (the vbases noted in the "Geography" section) are Rook bases that thus will shoot at both RAF and LW aircraft. If you don't want to get shot at by the auto gunners at these bases, stay out of the AA from these bases. (Consider the gunners at these bases to be twitchy and that they will shoot at any aircraft.)


1) JG & ZG gruppen may not carry bombs but have one life in their primary aircraft and one life in Ju 87's.

2) EG & KG gruppen may carry full bomb loads and have one life in their primary aircraft. KG have an additional life in Ju 88's. EG have an additional life in Ju 87's.

3) KG gruppen must set salvo to 20.

4) One KG gruppen may carry torpedoes each frame.

5) There are no launch time limitations.

6) JG & ZG may refuel and re arm at any available field.

7) EG&KG may only refuel and rearm at fields originally spawning bombers.

8) There are no altitude limits.

9) Between-Frame Relocation. Gruppen base fields can be moved around (between Frames, after Frame 1) within Jafu but not across Jafu. A staffel can be moved to a new base, but that new base must be in the same Jafu and must be one of the bases listed in the table in "LW Order of Battle". The staffel can be moved to a small airfield only if that small airfield will then have two or fewer staffel based there and to a large airfield only if that large airfield will then have four or fewer staffel based there. Ju 88 staffel can only be moved to large airfields that have Ju 88's enabled.

10) Downed LW pilots may take up gunner positions in ZG, EG and KG aircraft.

11) ZG, EG, and KG aircraft may take excess "walk on" gunners within arena limits.

12) Rescued LW pilots can re up after T = 60 minutes (see rescue below).

13) Damaged aircraft returning to their home/origin field may under go repair and re launch. Pilots returning to tower at other fields (unless under rescue rules) will not be able to re launch.

14) Pilots that have one life in primary aircraft and one life in secondary aircraft may fly at any time any aircraft in which they have a remaining life (e.g., they don't have to fly the primary first, may fly primary then secondary then primary if they didn't use up a life in primary, etc.).

15) Ju 88's may be used only for level bombing and, under the limits given above, torpedo bombing. They may not be used as divebombers.

Rescue Conditions

Rescue is available to all pilots who have bailed to ground or sea. Rescued pilots may not take off until past the T+60 minute mark in the scenario. In other words, if you bail or ditch, are picked up (rescued), and it is only 45 minutes after the initial starting takeoff in the scenario, you have 15 more minutes to wait until you can take off. After the T+60 minute mark, rescued pilots can take off right away.

Pilots who return to tower other than by landing at their assigned base or via the rescue rules below will be considered lost.

Pilots will wait to be picked up by rescue craft (Boat or Vehicle or Transport aircraft) or they will walk/swim to the nearest airfield, ship or port. Call on your country channel for rescue by one of your country's rescue craft -- please reserve channel 250 for calls for CM rescue verification as described below. Rescue happens when the rescue craft is next to the downed pilot. Thus, a PT boat or jeep must be next to the downed pilot. A C-47 must land and taxi to the downed pilot, or the downed pilot must run to the C-47, or both.

While pilots on the ground or in parachutes may not be shot at by enemy aircraft, if a pilot ditches his plane and stays in it (as opposed to bailing out on the ground), he can still be shot at and killed by enemy aircraft. It is recommended that pilots who ditch bail from their ditched aircraft.

Upon a rescue craft arriving to rescue a pilot, a CM must be called to authenticate the rescue. Where upon the pilot will return to tower and be available to fly again. Given this, the pilot will not be considered yet lost. Downed pilots ready for rescue authentication should tune to text channel 250, call for a CM to verify the rescue, give side you are on, and give precise location. Maps are divided up into sectors. We use the "dot" (or "keypad") location system to specify location within a sector. In this system, each sector is divided up into sections like the 1-9 keys on the keypad of your keyboard, as follows.

For example, the purple "x" is in sector 13.15, at a keypad location 6. In a scenario, you'd say that the purple "x" is in 13.15.6 (or verbally "thirteen dot fifteen dot six"). Furthermore, each keypad location can be further subdivided into a keypad. If you wanted to be even more precise, you could say the the "x" is in Use this more-precise method for reporting your location to the CM for authenticating the rescue. Thus, an example call for CM verify of rescue would be: "need cm verify, raf,".

Bailed pilots and rescue craft shall be considered inviolate and must not be attacked under any circumstances.

Rescue craft may not shoot at enemy aircraft or at enemy rescue craft.

Rescue craft (boats, transport aircraft, and ground vehicles) are limited to 2 per squadron or staffel at any time under all circumstances. Thus, the RAF may have up to 28 total rescue craft in operation at any one time, and the LW may have up to 38.

There is no limit to rescue craft lives. Rescue craft can launch from any base. Rescue-craft operators may exit to tower and launch from another base without needing to go back to base -- they can hop around as they see fit.

Non-dead pilots may do rescue duty for a while then get back to normal combat flying. For example, a pilot may land his fighter or bomber aircraft at his normal base (or be landed at his normal base already), launch a rescue craft from any base, hop around doing rescues, exit to tower from the rescue craft (without going back to any base), and take off from his normal base in his fighter or bomber.

Rescue Aircraft shall only operate over land and not cross into enemy territory.

There is no restriction to rescue craft origin. It is intended that rescue craft are always available. For PT boats, at ports where vehicle hangars are destroyed (and thus PT boats would be otherwise be unavailable), the CM's will note the destruction of the VH, notify the LW and RAF CO's that the port's vehicle hangar is destroyed (so that they know additional attacks on that VH are not needed), and then restore the VH so that the port can continue to launch PT boats. Note that if the port ends up not being neutralized (i.e., the VH and more than 50% of the port's town are not destroyed), the VH will need to be destroyed the next frame, as it is counted as repaired between frames. If the port is neutralized, then the VH need not be destroyed again and is counted as destroyed from then on.

Reasons for Various Rules

Ju 88's as divebombers

Ju 88's are restricted not to be used as divebombers since they are stand ins not just for Ju 88's but also for He 111's and Do 17's.

Special Frame 4

It is possible for the LW to achieve all of its objectives by the end of frame 3. If this happens, the LW wins the Battle of Britain, and frame 4 will be the following.

It's late fall in 1941, a year since the British Army, as well as civilians with pitchforks and torches repelled the invasion of England by German forces. Now Hitler is MAD and has tasked the Luftwaffe with the complete destruction of Southampton and London. With the new Me109F joining the battle, Hitler is certain that his bombers will get through and crush the morale of the Britains once and for all.

But don't count the British out yet! Churchill has pressed the RAF to deliver the latest versions of their frontline fighters, the Spitfire Mk V and Hurricane Mk IIC to repel the expected bomber raids that have started on beloved English cities.

Welcome to BoB Special Frame 4!

Rule changes are as follows.

Object damage

  • All airfields and buildings will be repaired prior to frame 4.
  • ROOK Radar vbases will be repaired prior to frame 4 and available for radar operators.

Object hardness

  • Hardness of Bombable, City, and Town objects will be set to 4.0 (i.e., 4000 lbs).
  • HQ hardness will be set to 24.0 (24,000 lbs).


  • Downtime will be set to 25 minutes, so that there are buildings to blow up on multiple runs.

Frame timings

  • The frame will run until T+3 hours, and then logs will close. When logs close, any plane not RTB'd will be considered lost. There will be no "end hostilities" call, just end frame.

Rescue, lives, and replaning

  • There will be no rescue; each pilot has two lives. Rearm anywhere is OK, and replaning at home base is still OK.

RAF Planeset

  • Spit squadrons get Spit V's.
  • Hurricane squadrons get Hurri IIC's.
  • Four Hurricane squadrons can fly Spit V's instead of Hurri IIC's if they wish.
  • Any aircraft capable of carrying drop tanks may do so.

LW Planeset

  • 109 squadrons will fly 109F's.
  • 110C squadrons can fly 110C or 109F's if they wish.
  • Ju 88 squadrons will fly Ju 88's.
  • All pilots can reup in their original planes for their second life, or Ju87 as stated in the rules for Axis.
  • Any aircraft capable of carrying drop tanks may do so.

Home airfields

  • Side CO's can move groups to other fields from the original set up to reflect the targets, with the exception of Ju88's.


  • Targets are London (bishop HQ city) and the city at Southampton (P107 city), and both need to be hit.


Scoring for frame 4 will be calculated by the formula as follows, and the score for frame 4 will be announced.

Scoring formula:

Victory judged, approximately speaking, by how many Ju 88's drop on target minus how many shot down plus 0.25 * (how many RAF fighters lost minus LW fighters and Ju 87's lost). Specifically, Victory is calculated from log as follows.

"Ju 88 Drops" = 3 * (number of Ju 88 pilots taking off on a mission) - (number of "Shot down a Ju 88A-4" messages prior to drop time for that mission). Drop times can be estimated by when "object destroyed" messages appear.

"Aircraft Losses" = deaths + bailed + captured + crashed + ditched.

Victory = (number of Ju 88 Drops) - (number of "Shot down a Ju 88A-4" messages) + 0.25 * (RAF Aircraft Losses) - 0.25 * (LW Aircraft Losses - number of "Shot down a Ju 88A-4" messages).

If Victory is > 0, then LW wins. If < 0 then RAF wins.
