Description

GarageImage Blenheim Mk IV.jpg


The Blenheim Mk IV is a Rank I British light bomber with a battle rating of 2.0 (AB/RB) and 1.7 (SB). It has been in the game since the start of the Open Beta Test prior to Update 1.29.

The Blenheim IV is a light bomber, therefore base bombing in Realistic Battles isn't recommended, as the armament of 2 x 500 lbs bombs isn't enough for one or two runs against a base. The Blenheim's advantage over other bombers is its speed, so remembering and implementing this into tactics is vital. Low and fast tactics are normally best, try to avoid flying at medium altitudes or high altitudes, as accuracy will drop and you will be weak against attacks from below. Although the "red-line" speed of the Blenheim is high, dive bombing isn't as accurate as level bombing, so try to fly very low over the target to ensure a hit with the weaker payloads. The front turret guns are excellent for the "drive-by" method of attack against un-armoured targets- this is an advised tactic to carry through to the Beaufort - the wing mounted gun was intended as a range finder in real life, but can ground attack un-armoured targets, with time and patience, although the turret method is easier.

The plane can also be used as a fighter. This is due to its supreme low-speed turn capabilities. The Blenheim turns into a Spitfire with flaps deployed, and the elevator fully extended. Surprising as it may sound, the frontal armament may prove devastating when used in a correct way. That is, if you load tracers, for not only unlike other ammunition choices it gives you a rough idea where the shells are going, but also it consists of the best shell composition, with a decent chance to light fires. As for the turrets, load universal, again due to its best shell composition.

The Blenheim can be absolutely deadly to other early planes, particularly as the biplanes it will be up against are often flown by inexperienced pilots who tend to position themselves right behind bombers at very close range while attacking -- in other words, their planes will be stationary relative to the gunner, and at such a close range that he simply cannot miss. Thus, a single Blenheim bomber picking off large numbers of enemy planes is a common sight. The Blenheim has one forward-firing weapon, but it's mounted far out on the wing, so hitting targets with it effectively requires some practice.

Armaments

Offensive armament

The Blenheim Mk IV is armed with:

  • 1 x 7.7 mm Browning .303 machine gun, left wing-mounted (500 rpg)

Suspended armament

      Main article: Bombs

The Blenheim Mk IV can be outfitted with the following ordinance:

  • 4 x G.P 250 lb Mk IV bombs (1,000 lb total)
  • 2 x G.P 500 lb Mk IV bombs (1,000 lb total)

Defensive armament

The Blenheim Mk IV is defended by:

  • 2 x 7.7 mm Vickers K machine gun, ventral turret (500 rpg = 1,000 total)
  • 2 x 7.7 mm Browning machine gun, dorsal turret (500 rpg = 1,000 total)

Usage in the battles

In order to be successful in shooting enemy aircraft, one needs to either immediately drop the bomb, or (on small maps like Bastogne, or Essen) dive down, and release on the first target spotted. Then it's just a matter of flying a plane like a Spitfire - turn fighting at low altitude, and sometimes stall fighting, and making all sorts of evasive maneuvers (though this might seem ridiculous, do not worry, the plane really is capable of supporting such handling). When turning it is important to remember that the plane will rip during sharp turns at speeds exceeding 350 kph. Obviously, at some point you will get an enemy on your tail. Then, your defensive gunners come into play. All you need to do is to swing the tail of the aircraft around, and fire at the enemy with either your top or bottom turret. It is also a good idea to first fire off all the ammunition in one of the turrets, and while it is reloading use the second one.

If you are down tiered, you can use your speed to completely avoid some enemy fighters. At a decent altitude (3,000 m or above works best), biplanes will not be able to catch you and low tier monoplanes will struggle.

One last thing about the turrets: they both have a 360 degrees firing arch. This means, that you may also use them offensively (especially when engaging bombers, with whom you may exchange broadsides, or when the offensive armament has run out of ammunition).

Pros and cons

Pros:

  • Very high speed for its rank
  • Great turn time
  • Forward-firing machine gun
  • Ventral and dorsal turrets on the same aircraft are rare at its tier
  • Excellent coverage for ventral and dorsal turrets
  • Defensive turrets are excellent against unarmoured aircraft

Cons:

  • Very vulnerable when the gunner is taken out
  • Turrets lack punch, particularly when compared to the Beaufort
  • Poor bomb load, even for its tier
  • Offensive machine gun lacks any firepower
  • No bulletproof glass or armour to protect the pilots from head on attacks

History

Making the first mission of WW2, then the next day, the first bombing raid, the Blenheim mk4 was a vital part of the RAF's early war effort. It became obsolete in 1942 as newer planes and technology made the Bristol Blenheim outdated. Dimensions : Length: 13.00 m Width: 17.17 m Height: 3.91 m
