قال مسؤول هندي يوم الاثنين ان الهند أجرت بنجاح تجربة اطلاق مقذوف أسترا جو- جو الذي تم تطويره محليا من قاعدة الدفاع في
Odisha
للمرة الثالثة في غضون أسبوع .
تم اختبار الصاروخ خارج المدى البصري من ميدان التجارب المتكاملة
(ITR)
في تشانديبور، حيث اعترض الصاروخ هدف المحاكاة.
"لم يكن هناك هدف فعلي، و لكن أعترضت بنجاح هدف محاكاة على ارتفاع 4 كم"،
حسب باراساد مدير ميدان التجارب المتكاملة
ويتوخى أسترا أعتراض وتدمير طائرات العدو بسرعة تفوق سرعة الصوت في وضع وجها لوجه و لغاية 80 كيلومترا وبوضع المطاردة لغاية 20 كم
وكان العلماء من (منظمة تطوير الابحاث الدفاعية) التي طورت المقذوف قد ذكروا انه قد تم أجراء اختبارات ناجحة للصاروخ استرا من نفس القاعدة في وقت سابق من يومي الجمعة والسبت.
"إن ممارسة التي نفذت الاثنين كانت لاختبار قدرة الصاروخ على الاعتراض والمناورة العالية،"
India successfully test-fires Astra missile third time in a week
India on Monday successfully test-fired its indigenously developed Astra air-to-air interceptor missile from a defence base in Odisha for the third time within a week, an official said.
The beyond-visual-range missile was tested from the Integrated Test Range (ITR) at Chandipur, about 230 km from here. The missile intercepted a simulated target.
"There was no actual target. It successfully intercepted a simulated target at an altitude of 4 km," ITR director M V K V Prasad said.
Astra is envisaged to intercept and destroy enemy aircraft at supersonic speeds in the head-on mode at a range of 80 km and in tail-chase mode at 20 km.
The scientists of the Defence Research and Development Organisation (DRDO) which developed the missile had earlier conducted successful tests of the Astra missile from the same base on Friday and Saturday.
"The exercise carried out Monday was to test the missile's interception capability and high manoeuvring," he pointed out.

Astra (missile)
Astra[4] (Sanskrit: अस्त्र, Astra "Weapon") is an active radar homing beyond-visual-range air-to-air missile (BVRAAM) developed by the Defence Research and Development Organisation (DRDO), India. Astra is designed to be capable of engaging targets at varying range and altitudes allowing for engagement of both short-range targets (up to 20 km) and long-range targets (up to 80 km) using alternative propulsion modes. As of May 2011, the missile is undergoing developmental trials.
Description
The missile guidance is provided by a terminal active radar-seeker and an updated mid-course internal guidance system, which locates and tracks targets. On-board electronic counter-measures jam radar signals from enemy radar, making tracking of the missile difficult. The performance characteristics of the missile are similar to the R-77RVV-AE (AA-12) and Super 530D, both currently used by the IAF. It is 3.8 metres long and is narrower in front of the wings. The propellant used is HTPB (solid-fuel). The warhead is a 15 kg HE (high-explosive) which is activated by a proximity fuse. The missile's maximum speed is Mach 4 and can attain maximum altitude of 20 km. The missile can handle 40 g turns near sea level while attacking a manoeuvring target.
Performance
The maximum range of Astra is 110 km in head-on chase and 20 km in tail chase. The missile could be launched from different altitudes - it can cover 110 km when launched from an altitude of 15 km, 44 km when fired from an altitude of eight km and 21 km when the altitude is sea-level . The missile can reportedly undertake 40 g turns close to sea level, when attacking a maneuvering target. It will have an active homing range of 25 km. The missile has a pre-fragmented warhead and is fitted with a proximity fuze.[2] A radar fuse already exists for the Astra, but the DRDO is currently working on a new laser fuse. Astra has on-board ECCM capability allowing it to jam radar signals from an enemy surface-to-air battery, ensuring that the missile is not tracked or shot down. The Mark 2 version of Astra will have a maximum range of 150 km and tail chase range of up to 35 km.
