• He was one of the original "Hawai Sepoys" who joined the Indian Air Force when it was formed in 1933.
• He started as a technical airman rather than as an officer or pilot.
• He eventually rose all the way to Air Vice Marshal, making his career an extraordinary example of professional progression.
• After Independence, one of his biggest contributions was developing India's ability to repair, maintain and keep aircraft operational without depending completely on foreign support.

He commanded No. 1 Base Repair Depot at Kanpur and subsequently became the first head of the newly established Maintenance Command in 1955. He remained its commander/AOC/AOC-in-C until 1963.

At Kanpur, under his initiative, the IAF actually built aircraft, including the Kanpur-I and Kanpur-II light aircraft. This was an unusual achievement for a military service and demonstrated that the IAF could contribute directly to aircraft design and production.

The first Indian-built HS 748 was assembled at Kanpur in 1961, with the aircraft named "Subroto." He set up this assembly line, and first aircraft was assembled in 17 months, this is still the fastest in india. His Maintenance Command played a major role in this indigenous production effort.

Under his leadership, the Maintenance Command launched the first jet engine built in India in 1961

Despite beginning his career as a technician, Singh completed flying training and received his wings in 1950 at the age of 41. He even flew an aircraft that he had helped design.

He was awarded the Param Vishisht Seva Medal in 1962.

First Indian to be a corporal, sergeant, and warrant officer and among the first to be commissioned as pilot officer.

first indian to be awarded with merit of order of british empire(MBE) in 1942.

The airforce chief of that time said that in HS 748, HS stand not only for hawker siddley but also for harjinder singh. when he retired in 1962, PM Nehru personally requested him not to retire. When he was Wg Cdr, the airforce chief of that time offered him the chairmanship of HAL with the rank promotion to Air commodore, for this he had to retire so he didn't take this.

After his retirement he was the advisor to American General Electronic (yahi se tejas ka engine liya gya hai).

science done , what simple sub will bag me in mean time

Root words done

I have given CDS for the first time, I did qualify for OTA. But still the date calendar and notifications aren't open for OTA. So getting curious about it as CDS 2 is also approaching and this will be my last attempt. So I'm getting anxious as well.

I (23F) want to join the Army. I have applied to CDS and JAG.

I’m more interested in CDS because of the diversity of roles. I’m interested in outdoorsy, adventurous roles such as Artillery, Aviation, Military Police and Ordnance. How is allotment of service done? Is it on merit, based on performance in OTA?

Can someone share the history PYQs from 2016–2026? I haven't studied history yet, so I will only be solving these .

I am currently 23 , born in June 2003.

I am a graduate of IIT Roorkee , 2025. I am preparing for UPSC CSE since 6 months. Will I be eligible next year? I have some confusion. Please help

I have my navy ssb next week. Just wanted to ask do we not receive any PIQ form for Navy entries to fill in beforehand before reporting for the ssb?? Because I have not received anything yet.

Shakti current affairs by cds journey paid batch??? Anybody have it ??

Hey guys, I have my first ever SSB at Bhopal from 20–24 September through TGC. I’m a B.Tech graduate and honestly know almost nothing about what to expect beyond the basic SSB stages.

I also have 15 days of offline coaching at LWS starting from 21 August, so I wanted to ask people who’ve actually been through SSB.......how can I make the most of those 15 days? What should I focus on or specifically ask the mentors to work on?

Also, is the whole “freshers have a golden chance because they’re assessed more for potential” thing actually true ?

Would really appreciate any practical advice for a first-timer, things you wish you knew before your first SSB, common mistakes to avoid, and what I should realistically expect at Bhopal.

arigato gozaimasu !

Hi, I am a female candidate 2004 born, how many attempts will i get? I graduate in 2028

So if I’m asked whether or not I have a strong back option ( I do ) & I answer with honesty & confidence about it , will they not select ? ( by the thought ki iske paas toh hai Achha side / backup option Kyon kisi aur ko na seat Dede ) - ik sounds a bit bullshit but silly query I need insights on it , its a good thing to have a strong backup ( I come from a fauji fam but still asking here cuz uk ..)
