Wait a minute, so how come Chobam designed a radome that could fit the Tejas?

@Anish9500 I think you need to calm down...Yes the Tejas project is not the best example out there but they are now correcting their mistakes moving forward ...though, quite late. The airplane itself is not bad but the management and planners are to be blamed. If Tejas was inducted early and improvements were done along with time, It would be a very credible aircraft for IAF.(JF-17 is a good example.Slowly and steadily, one wins the race). Still, Tejas project can be a serious threat to PAF when it completely materializes. Accountability and course correction is the way forward!
The Belgian Rattlesnake: Why the Lewis Gun was Feared and Revered for Three Decades
10/05/12 | by Kristin Alberts
The Lewis Gun was the child of a world torn apart by warfare. What do you know about the first machine gun ever to be fired from an aircraft? This is a weapon that functioned reliably under horrible trench warfare conditions in The Great War, was mounted to aircraft and Navy vessels through World War II, earned a fearsome nickname, and saw service with well over a dozen countries, yet seems largely forgotten today. No more.

The Lewis Gun
The Lewis Automatic Machine Gun was gas operated and capable of firing 500 to 600 rounds per minute. It was chambered first in .303 British, then in .30-06 Springfield, both of which produced muzzle velocities around 2500 to 2600 fps. Lesser numbers were later chambered in 7.92×57 Mauser. At a mere 28-pounds, the Lewis Gun weighed only half as much as its counterparts. It was known as much more portable than say, the Vickers or Maxim, as it could easily be carried and operated by a single soldier. This light machine gun was easily recognized both by the large aluminum cooling shroud encasing the barrel as well as its top-mounted drum pan magazine, which could hold either 47 or 97 rounds and stood in stark contrast to all other belt fed machine guns of the time.
History
Invented in 1911 by then U.S. Army Col. Isaac Newton Lewis, the Lewis Gun drew heavily from earlier designs by Samuel McLean. In spite of the weapon’s ties to the Army, it was never warmly embraced by such. You see, Newton and the U.S. Chief of the Ordnance Department, Gen. William Crozier, suffered from some sort of political-personal differences. Thus it came to be that what could have been known as one of the most portable, light, ingenious machine guns of its time never got its just due in the great US of A.
After unsuccessfully pitching his brainchild, Lewis grew frustrated in his attempts to persuade the Army to adopt the design to which he had dedicated his life, and so resigned his Army commission to pursue production abroad. By 1913, Lewis had found a warm home in Belgium where he started the Armes Automatique Company in Liege. There, he commenced commercial production of what he called the Lewis Automatic Machine Gun. Concurrently, Lewis was also in contact with the Birmingham Small Arms Company (BSA) in Great Britain, who expressed interest in his weapon.
In that same year of 1913, the Belgian Army officially adopted his design. They are known as the first parents to this .303 British round. It is said that when Germans first encountered the Lewis Gun while in combat with the Belgians in 1914, they were in such fear of the Lewis gun’s maneuverability, rapid and accurate fire, it came to be known as the “Belgian Rattlesnake.”
Shortly afterwards, BSA acquired a license from Lewis to manufacture the Lewis Machine Gun in the UK, which made him a wealthy man through the incoming royalties.
With the beginning of WWI, demand for this portable machine gun spiked, and BSA began mass production of what they called the Model 1914. Thus began a long, and well-traveled history of Col. Lewis’s vision for a new weapon which filled a niche in a world at war.
The design
The most noticeable feature of Lewis’ gun was the aluminum barrel shroud, which provided forced air draft cooling. While this casing was meant to use the muzzle blast to pull air into the gun for cooling, many doubted its usefulness and speculated that perhaps its sole purpose was one of appearance, as the gun functioned flawlessly in the field without it. Many of the shrouds were removed, especially on those aircraft mounted guns, a tactic which also saved several pounds from the weight of the gun.
The gun featured raised blade and tangent leaf sights, a front-mounted folding bipod, a wooden rear stock that could be replaced by a handle for maneuverability, and was listed to have an effective range of 800 meters and a maximum range of 3,200 meters.
Though Lewis’ machine gun remained significantly more expensive to manufacture than the Vickers, it could be put together twice as fast. In addition, while the Vickers required a water siphon cooling tank and the less-compact belts of ammo, Lewis guns were more mobile and versatile given the weight, air cooling system, and 97-round drum magazines. Lewis’ adjustable clock-type recoil spring allowed the gun’s firing rate to be regulated. Though it was capable of 500 to 600 rounds per minute, shorter bursts of fire were most common.
Who used it
Following its successful debuts in Belgium and Britain in early 1917, both the U.S. Navy and Marine Corps adopted the M1917 Lewis Gun, manufactured by Savage Arms Company and chambered in .30-06 Springfield.
In spite of this, the U.S. Army never officially adopted the widely available Lewis Gun for infantry use, instead waiting on availability of the Browning Automatic Rifle, which did not reach front lines en masse until late 1918. Whether this is due to the rift between the two men can never really be proven. However, the Navy and Marines continued to use the .30-06 M1917 into WWII, and the U.S. Coast Guard also mounted many Lewis guns to its vessels.
Shortly thereafter, the Russian Empire purchased 10,000 Lewis Guns from the British and another 10,000 from the U.S., though it is not clear how many were actually delivered. The Germans were so pleased to capture Lewis Guns in the field that they wrote a special manual and included instructions for its operation as part of their machine gun crew training, using the gun under the name MG137e. Cloning the Lewis Gun, the Japanese launched its Type 92 chambered in 7.7mm rimmed, a round very similar to the .303 British.
An aircraft’s best friend and worst enemy
Because of its portability, as well as the fact the cooling shroud could be removed, the Lewis gun found regular use as an aviation-mounted machine gun. In fact, the Lewis Gun will forever be known as the first machine gun successfully fired from an airplane.
In June 1912, Capt. Charles Chandler of the U.S. Army fired a prototype Lewis Gun from a Wright Model B Flyer.
Many French and British aircraft during WWI were fitted with the Lewis gun and its self-contained 97-round magazines. They were also loaded with incendiary rounds and used as balloon-busters targeting enemy dirigibles.
Not only was the Lewis gun used as an aircraft mounted weapon, it also saw expanded service as an anti-aircraft weapon during World War II. The Brits found it second to none at bringing down low-flying enemy aircraft, accounting for more such takedowns than any other British anti-aircraft gun of its time.
Downfall of the Lewis
The Lewis gun reached its peak of service during WWI, though it was said to be used by forces operating against the United Nations in the Korean, First Indochina and Vietnam wars. By the time the end of WWII had rolled around, the Brits supplanted the Lewis with the Bren Gun for infantry use and the Vickers for airborne. American forces kept the -06 caliber Lewis in service throughout WWII, though its popularity faded after the BARbecame readily available.
Though the heydays of the Lewis ended long ago, bits of Col. Lewis’s insightful designs—including the clockwork spring and self-contained drum pan mag—went on to drive the development of other weapons, including the German FG42 and, consequently, the M60.
By the time the final Lewis gun was produced in 1946, around 150,000 of them had been put into circulation. Not bad for a gun that, without the belief and dedication of its maker, may not have ever been.

Because we gave out a detailed global tender with specifications.

Nah, we will manage with outsourcing some of them while setting up production facilities to manufacture the same. After all we don't have to contend with 60% work share of the airframe.
It's well known by now in IAF that the Tejas presents the greatest opportunity and opening ever to the PAF which has been effectively denied since 1971.
We will NOT let you have the technical edge ever again. Even if we have to fight the entire domestic defence industry but we will keep our air superiority over you permanently.
The Tejas will be buried 10 feet under before we let it deploy to WAC/SWAC.

You should stop calling it indigenous or I'll start counting the foreign components.

Sure & I'll start counting the indigenous components.
If you can call something like JF 17 with so few Pakistani subsystems as a JV, we can call LCA indigenous.
or you can start with something non Indians- like this.

'Quartz' Radome, not 'a radome'. Hal did deliver it by the time production started. The counter question is how are so many dozens of JF 17s fielded without these. I'm assuming now they'll never get that upgrade.

I m not interested in Bla bla comparisons. Talk about Tejas and stick to it. Start counting indian components.

bhai, you know according to @Dazzler bhai quartz radomes aren't composite material. I guess they shape them out of solid quartz crystals with chisels...
Sure, it's only a problem when Indian does it.
I had made numerous posts on the same & you can try searching for them.
