You just tested it for the first time and declared it a success? How convenient, anymore revelations about the super duper interceptor missile? Last i read your Akash was rejected by your forces. How many tests are required to declare a system ready for induction? You must celebrate your success, it is your right, but after each test, stop inducing the same false stinky rhetoric that you and some of your fellow countrymen are known for.
Dear sir,
There is an old saying in India - "Alp Buddhi Bhayankari", which in essence means, gaps in Knowledge, is counter productive. Please read the following and update your idea of the "You just tested it for the first time and declared it a success?", such ignorance by a member of you imminence just makes your rhetoric looks foolish.
Advanced Air Defence (AAD)/Ashwin Ballistic Missile Interceptor
Advanced Air Defence (AAD) is an anti-ballistic missile designed to intercept incoming ballistic missiles in the endo-atmosphere at an altitude of 30 km (19 mi). AAD is a single-stage, solid-fuelled missile. Guidance is similar to that of PAD: it has an inertial navigation system, midcourse updates from ground based radar and active radar homing in the terminal phase. It is 7.5 m (25 ft) tall, weighs around 1.2 t (1.2 long tons; 1.3 short tons) and a diameter of less than 0.5 m (1 ft 8 in)
Trials conducted:
1> November 27, 2006, Wheeler Island
2>December 6, 2007, Wheeler Island
3>March 6, 2009 ,Wheeler Island
4>March 14, 2010, postponed to next day due to Technical glitch in telemetry
5>March 15, 2010 Test Aborted after Target missile malfunctioned.
6> July 26, 2010, Last Trial test, Wheeler Island
7> March 6, 2011, Production unit test.
8>April 07,2015, InterceptorTest failure
9> May 15 2016, AAD renamed Ashwin, test, Kalam island (Previously Wheeler Island)
Now to address your question about how many tests are needed for induction:
It depends on the system, a simple system like small arms ammunition can take about one test, QC certificate from the supplier and First article inspection for Induction, to a missile system, going through prescribed trajectory and testing protocol for validation of all flight mode parameters to an aircraft which would need DGQCA certification, hot weather trials, cold weather trials, High altitude trials and desert condition trials. If anything Indian testing protocols are stringent enough that even local projects cannot bypass the conditions and the test results are actually published and there is public accountability for these projects. So it depends on the system and type of validation needed for induction before any test regimen is designed.
To quickly address your akash system query;
Indian Air Force : 8 Akash squadrons + 7 on order (each squadron has 125 missiles ~ 1875 missiles total)
Indian Army : 2 Regiments = 12 squadrons (each squadron has 165 missiles - 2000 Missiles Total)
In June 2010, the Defence Acquisition Council (DAC) placed an order of the Akash missile system, valued at ₹12,500 crore ($2.8 billion). Bharat Dynamics (BDL) will be the system integrator and nodal production agency for the Akash Army variant
In March 2011, a report indicates that the Indian Army has ordered 2 Akash regiments — approximately 2,000 missiles — worth ₹14,000 crore ($3.1 billion).
On 5 May 2015 Akash Missile was inducted into the Indian Army.
On 11 April to 13 April 2015, Indian Army successfully conducted six rounds of user trials of the missile. The tests were conducted from complex 3 of the Integrated Test Range (ITR) at Chandipuri in Odisha. The missiles targeted pilot less target aircraft (PTA) Lakshya, unmanned air vehicle (UAV) 'Banshee' and a para barrel target, two times each
The Indian Air Force has deployed Akash at its bases in Gwalior, Hashimara, Tejpur, Jorhat and Pune
The Indian Army has deployed one Akash Regiment in June-July 2015 with the second one to be ready by end of 2016
Hope that helps
cheers
