IN air combat, the purpose of the fighter pilot and flexible gunners is to destroy the enemy quickly with the minimum amount of ammunition. This can best be accomplished by developing superior firepower, and firing at decisive range, which depend on:
Concentration of firepower may be considered in two parts, viz: Concentration of fire in time and space depending upon the number of guns that can be brought to bear either from a single aircraft or from a formation; bullet density built up during fire, depending on time and range.
The area of space covered by the fire from a single gun is termed the "bullet group" for that gun.
The primary consideration is to obtain a bullet density which is likely to destroy the expected target.
The total "lethal area" of a target is the sum of the various small vulnerable or vital areas in the target in which it is probable that one bullet would result in disabling or destroying one target aircraft.
Bullet density and the size of the bullet group are directly proportional to range, i.e., the diameter of the group at 400 yards is four times that at 100 yards.
It is imperative, in air combat, that a lethal density be built up quickly because
A fundamental of all air fighting tactics is simplicity and flexibility. Tactics must be simple because of the time factor. The speed of modern aircraft does not admit of the development of elaborate formations and attacks. Other factors which demand simplicity are
Another fundamental affecting fighting tactics is morale and leadership. A high morale is essential. It is dependent upon physical fitness, environment, a contented frame of mind and good leadership.
The leader must possess initiative and skill to judge when and from which direction maximum fire should be brought to bear. He must inspire confidence in air crews and know their ability and limitations. The good leader will aim to achieve a decisive success with the whole force under his command rather than to gain a personal victory.
Surprise is an important factor in air fighting. A leader should maneuver to achieve surprise before attacking, if possible. Surprise may be achieved by
When enemy aircraft are sighted in one direction, vigilance in other directions must not be relaxed. More often than not other supporting aircraft will be in the vicinity and to launch blithely into the attack on the first enemy seen without a quick search for other enemy planes is a sure way to be shot out of the sky and never know what hit you.
Before taking off or landing, search the sky for enemy aircraft. It is during these moments that your aircraft is most vulnerable.
If you hear gunfire, or see bullets hitting close to you or observe tracers going past immediately take evasive action then look around. Don't try to look before starting to turn. It might be too late.
Develop a rubber neck. Keep the sky under constant surveillance.
Watch your tail.
Never fly or dive straight when being attacked by aircraft or antiaircraft fire.
Fighters should endeavor not to close in on the enemy at too high a speed during the final stage of the approach or the burst of fire will be too short to be effective, or you may overshoot altogether.
Don't go into the middle of a V of enemy bombers. Attack them from the flank, and from both flanks simultaneously, where possible.
When you are going into the attack, don't give the enemy a chance at a deflection shot at you. As far as you can keep your nose on the enemy, and approach his blind spots as much as possible.
In attacking enemy bombers don't fire a long burst if enemy fighters are about; two seconds is long enough. Then break away quickly and look about to be sure no enemy fighter is after you. If all is clear you can take another crack at the bombers, if necessary.
Don't break away in a climbing turn. This gives an easy shot to the enemy rear gunner.
Don't leave your formation, if you can help it, unless ordered to do so.
Don't ever fly straight, especially if you are alone. Keep that rubber neck turning continuously and keep a lookout behind.
Don't let the enemy slip out of the sun to get you. In looking toward the sun place a finger or thumb before your eyes.
Don't waste ammunition by firing at long range.
A large formation is more vulnerable to antiaircraft fire than a number of small formations. The larger the formation the less maneuverable it becomes. However, it is more likely to subject attacking aircraft to a superior concentration of fire. With a large formation there will be a tendency for a number of gunners to fire on a few enemy aircraft and to ignore others, and to waste ammunition. There is, therefore, a limit to the size of a formation to obtain economical fire concentration. Aircraft which have blind sectors, or sectors of reduced firepower, need larger formations than those which have all round arcs of fire.
Small formations are less easily seen than large ones.
Every pilot must be able easily to see the aircraft on which he is formating. All aircraft in the formation must keep station on the leader, and as few as possible in sequence. Otherwise accumulated errors build up and the rearmost pilots have a very difficult task in maintaining proper position.
While being attacked, make it impossible to draw a straight line from the enemy aircraft line of approach through two or more aircraft of the formation. Otherwise the attackers may successfully enfilade the formation.
The length of the formation should be equal in all directions, where possible.
All aircraft in the formation, with possible exception of the leader to be equidistant from the enemy aircraft. Thus in defensive bomber formations every aircraft should be spread perpendicular to the enemy's line of approach.
Aircraft in formation should be sufficiently far apart to avoid one plane being hit by shots aimed at the other. At the same time they must be sufficiently close to provide maximum mutual support.
Formations disposed in depths create a large volume of slipstream turbulence which, when bombers are being attacked from rear, throws fighters off their line of sight. The ideal defensive formation will differ with every method and direction of attack. Each formation must, therefore, possess sufficient flexibility to allow a quick alteration to some other formation.
The disposition of aircraft in formation will depend upon circumstances. For example, if attack on a defensive bomber formation is developing from above, aircraft in the formation should be stepped down if the attack is from below the aircraft should be stepped up. If the attack is from the same level and developing from the beam aircraft should be stepped down (for it is easier for fighters to sweep a formation upwards than downwards. With aircraft on the nearer flank down and on the outer flank up.)
When encountering antiaircraft fire, aircraft in all sections should be far enough apart to avoid more than one aircraft being brought down by any one antiaircraft burst.
Always turn toward a hostile fighter. Thus you shorten his approach, and therefore make him turn more rapidly. Maybe he won't be able, aerodynamically, to turn fast enough and he may be forced to break away. Do not turn away from the direction of attack. A straight dive will give enemy aircraft a "sitting shot." You actually appear as a stationary target in such a dive either at a target plane or away from the plane.
Never change from one turn to a reverse turn. Wait for a brief interval between attacks. Take a quick look about before launching successive attacks.
When hedge hopping, or flying low over the sea, fly an erratic course.
Clouds, except the smallest ones, afford one of the best means of avoiding enemy aircraft. When possible fly near the clouds, but if over areas covered by antiaircraft fire, do not fly immediately below the cloud base, as antiaircraft can accurately determine the range from the cloud base.
Do not fly straight through a cloud when avoiding enemy aircraft. Alter course in the cloud to turn towards the enemy.
Aircraft flying about 20,000 feet are difficult to see from the ground.
Avoid layers of air in which white streamers form astern.
At night do not open throttle because this increases length of exhaust flame which can be seen at long distances.
Show no lights on your aircraft.
Searchlight beams without accompanying antiaircraft fire indicates presence of enemy fighters. Do everything possible to get out of the light.
To evade enemy fighters, fast bombers may be sent in advance of the striking force, to draw off enemy fighters. Also planes may be routed on dog-leg courses toward other important objectives with a view of deceiving the enemy as to the actual target.
Sound locator crews usually do not allow sufficiently for the lag in the time it takes the engine noise to reach them which results in searchlights and antiaircraft fire being below and behind. (Recently, it seems, German antiaircraft must be directed by radio-locators. Where radio-directed antiaircraft fire is encountered some of the foregoing suggestions, therefore, will not apply.)
In seeking to avoid searchlights, turn. A climb or dive, without turn is ineffective.
The antiaircraft gunner's greatest difficulty is finding the correct elevation. Consequently a change in height, as well as turning is the best method of evasion. Effective danger area of 3-in and 4.5-in shells is from 30 to 90 feet radius. The area behind and below the bursts is usually safe, therefore, it is best to fly below shell bursts rather than above them.
When within range of enemy antiaircraft it is imperative that course and altitude be altered continuously to avoid destructive hits. Heavy antiaircraft fire is most accurate between 6,000 and 18,000 feet; therefore, if possible, fly above or below these heights.
The ideal target from antiaircraft point of view is a large formation in line astern. The most difficult for antiaircraft are small sections (of two or three flying line abreast, or shallow echelon, at different heights.
At night it has often proved effective to drop a flare or other object, and then dive or climb on a turn. The enemy antiaircraft often concentrate on the flare or other object, and thus enable you to get away.
Short range antiaircraft is usually ineffective at heights above 5,000 feet. Therefore fly at greater heights, or else very low.
Attacks against defended areas should be made suddenly and not repeated for at least five or 10 minutes. Make a low and quick getaway without trying to maneuver to observe effect of your attack.
Low-flying attacks should be made from the direction of the sun, or from clouds and by taking advantage of topographical features. If both short-range and long-range antiaircraft fire is expected, the best compromise is to fly at about 5,000 feet, at ground level, or above 18,000 feet.
Physical condition cannot be overemphasized. A tired, exhausted, or poorly conditioned flyer is cold meat for a well conditioned adversary. Top physical condition will not just come of itself. It must be cultivated. Proper exercise, adequate rest, between operational flights will pay the biggest dividends. Sound physical condition will contribute to a high morale, instill an eagerness to get on with arduous tasks, insure the successful operation of the unit.
