To be called 'Rajju Bhaiya Sainik Vidya Mandir', the school will be set up in Shikarpur tehsil of Bulandshahr district, where the former RSS sarsangh chalak was born in 1922.
The school will be run by Vidya Bharti, the education wing of the RSS, and will offer defence training to students.
The RSS Army school will follow the Central Board of Secondary Education (CBSE) curriculum and will have students from Class 6 to Class 12. The classes are set to begin from April 2020 and its first batch is expected to comprise 160 students.
Vidya Bharti already runs over 20,000 schools across India.
The construction of the residential school for boys has already begun on the 8 acre land donated by ex-Army man Chaudhary Rajpal Singh.
According to reports, the three-storey building will have a hostel, quarters for staff, a dispensary and a stadium.
Samajwadi Party (SP) President Akhilesh Yadav has questioned the need of opening another army school.
"The project is likely to entail an expenditure of Rs 40 crore. We already have five military schools in the country, of which two are in Rajasthan, two in Karnataka and one in Himachal Pradesh. There is also a Sainik school in Lucknow and one each in Jhansi, Amethi and Mainpuri. These institutions are run by the government so where is the need for RSS to run its own army school," he said.
Yadav said that the RSS apparently wanted to serve its political purpose by opening the army school where the students will "probably be taught lessons in mob lynching and disrupting social harmony".
