Let me be honest with you for a second.
Most “internship” opportunities floating around LinkedIn and college notice boards right now are unpaid, vague about what you’ll actually do, and forgotten the moment you graduate. You do the work, get a generic certificate, and move on.
This one is different.
The Terminal Ballistics Research Laboratory (TBRL) — a premier lab under DRDO, Ministry of Defence — has quietly opened its Paid Internship 2026 for engineering and science students across India. Six months. ₹5,000 every month. A DRDO certificate at the end. And real defence research work in between.
The catch? Last date is 25 May 2026. You don’t have weeks — you have days.
Here’s everything you need to know.
Why a DRDO Internship Hits Different on Your Resume
Before we get into eligibility and forms, let me tell you something your placement officer probably won’t.
DRDO — the Defence Research and Development Organisation — is India’s top defence R&D body. TBRL specifically works on terminal ballistics and defence testing. Getting an internship here isn’t like getting one at a random startup that calls itself a “tech company.”
When a recruiter — whether at a PSU, a core engineering firm, or a government body — sees DRDO TBRL on your resume, it tells them three things instantly: you cleared a merit-based selection, you worked in a high-security technical environment, and you stuck with something for six months.
That’s the kind of signal that actually moves the needle. Not a 2-month unpaid “marketing intern” role.
The Basics — What This Internship Actually Offers
| Detail | Info |
|---|---|
| Lab | Terminal Ballistics Research Laboratory (TBRL) |
| Under | DRDO, Ministry of Defence, Govt. of India |
| Ad Number | TBRL/HRD/PDINTERN/2026/01 |
| Duration | 6 Months — July to December 2026 |
| Stipend | ₹5,000/month → ₹30,000 total |
| Location | TBRL Range Ramgarh, Panchkula, Haryana |
| Last Date | 25 May 2026 |
| Mode | Offline application by post |
| Official Site | drdo.gov.in |
The ₹30,000 is paid in two instalments — ₹15,000 after Month 3, and ₹15,000 after Month 6. It goes straight to your bank account.
Are You Eligible? Check This First
Two categories of students can apply.
Category A — B.Tech / B.E. Students
You’re eligible if:
- You’re in 6th semester or later (3rd or 4th year of a 4-year degree)
- Your branch is one of the eight listed below
- You have 75% or above across all completed semesters (CGPA must be converted to % by your college — not self-calculated)
- You have zero active backlogs
- Your internship is part of your degree curriculum — not just a personal initiative
- You are under 28 years of age as on 30 June 2026
Category B — M.Sc. Students
- 2nd year M.Sc. Chemistry students only
- Same 75% marks and no-backlog rule applies
- Internship must be curriculum-linked
One rule TBRL repeats twice in their advertisement — no equivalent or related branches will be considered. Your branch must match exactly what’s listed. No exceptions, no appeals.
Seats Available — Branch-Wise Breakdown
B.Tech / B.E. (Category A) — 35 Seats
| Branch Code | Branch | Seats |
|---|---|---|
| AER | Aerospace / Aeronautical Engineering | 03 |
| CHE | Chemical Engineering | 01 |
| CSE | Computer Science Engineering | 07 |
| ECE | Electronics & Communication Engineering | 09 |
| INE | Instrumentation Engineering | 01 |
| MEE | Mechanical Engineering | 08 |
| CIE | Civil Engineering | 04 |
| ELE | Electrical Engineering | 02 |
M.Sc. Chemistry (Category B) — 2 Seats
Total: 37 seats across both categories.
ECE has the highest intake at 9, followed by Mechanical at 8 and CSE at 7. Chemistry M.Sc. has only 2 seats — if that’s your discipline, apply early and make sure your application is spotless.
How Stipend Payment Actually Works
A lot of students I’ve spoken to assume the ₹5,000/month just shows up automatically. It doesn’t — there’s a condition attached.
You must complete a minimum of 15 working days every month to be eligible for that month’s stipend. Fall below 15 days — even once — and that month’s payment is withheld.
The only leave permitted during the internship is sick leave, and only with a valid medical prescription. No casual leave. No personal leave. This is a defence establishment — they run it like one.
⚡ Pro-Tip: If you’re travelling from another state, factor in your journey time before the 1st July start date. Arriving late and missing your first week counts against your 15-day attendance for that month.
Step-by-Step: How to Apply for TBRL DRDO Internship 2026
No online form here. This is a physical application sent by post. Here’s the exact process:
Step 1: Download the Application Form
Go to 👉 https://drdo.gov.in and download the prescribed application proforma. Using any other format will get your application rejected — no questions asked, no second chance.
Step 2: Get Your College to Write the Request Letter
This is non-negotiable. Your Principal, HOD, or TPO must write a Request Letter on college letterhead, in the exact format provided in the TBRL advertisement. The letter must:
- Confirm the internship is part of your degree
- Confirm you’ll attend minimum 15 working days/month
- Carry the official college seal and signature
No letter = no application. TBRL won’t process incomplete submissions.
Step 3: Fill the Application Form — Carefully
Fill it in capital letters only. Double-check:
- Name exactly as on Aadhaar
- Correct branch code (AER, CSE, ECE, etc.)
- Cumulative average % calculated correctly across all semesters
- Email ID — this is how selected students are contacted
Step 4: Compile Your Documents
Pack the following together:
- ✅ Filled application form with passport photo affixed
- ✅ Request letter from Principal/HOD/TPO (prescribed format)
- ✅ Mark sheets of all completed semesters
- ✅ Aadhaar card copy
- ✅ College ID card copy
Step 5: Label Your Envelope Correctly
Write on the top of the envelope:
“Application for Paid Internship: Starting July 2026” “Branch Code: ___________”
This helps the HRD Division sort applications faster — and yes, they do check.
Step 6: Post It to This Address Before 25 May 2026
The Director Terminal Ballistics Research Laboratory Defence Research and Development Organization Ministry of Defence, Government of India Sector-30, Chandigarh – 160030 (Attn: HRD Division)
Use Speed Post or Registered Post — save the receipt and tracking number. Applications arriving after the deadline are rejected outright, and TBRL will not respond to queries about late submissions.
What Happens After You Apply
Here’s the timeline so you’re not checking your email every hour wondering what’s going on:
| Stage | When |
|---|---|
| Last date for application | 25 May 2026 |
| Shortlisting & interviews | June 2026 |
| Intimation to selected students | 3rd / 4th week of June 2026 |
| Internship begins | 1st July 2026 (tentative) |
Selection is based purely on your cumulative marks percentage across all semesters. If two candidates have identical marks, the older one (by date of birth) gets priority. Shortlisted candidates may also face a telephonic or online interview.
Only selected students are contacted — by email, to the address you write on your application form. There is no rejection communication. If you don’t hear by late June, you weren’t selected this cycle.
If You’re Selected — Documents to Keep Ready
The moment you get that selection email, start collecting these. Some take time:
- TPO letter for 6-month duration
- Bonafide and Character Certificate from college
- NOC from college on letterhead (original)
- Police Verification Certificate from your hometown ← start this immediately
- Aadhaar card original
- All original mark sheets
- 3 passport size photographs
- Bank account details
The police verification is the one that catches people off guard. It takes anywhere from a few days to a few weeks depending on your local police station. Don’t wait until a week before joining to initiate it.
Frequently Asked Questions
My college uses CGPA. How do I show 75%? Your college must officially convert your CGPA to percentage using their own formula and mention it in the Request Letter. TBRL will not accept a conversion you’ve done yourself.
Can I apply if the internship isn’t mandatory in my course? No. It must be a formal part of your B.Tech or M.Sc. degree curriculum. Voluntary internships don’t qualify.
I cleared a backlog last semester. Am I eligible? The advertisement says students with backlogs are ineligible. If your backlog is fully cleared and doesn’t reflect as active on your current record, you may proceed — but do not hide or misrepresent it. Suppression of facts leads to disqualification at any stage.
Will DRDO offer me a job after the internship? No obligation exists on TBRL’s part, and interns cannot claim any employment right. However, the experience and certificate are valuable assets for DRDO recruitment exams (like CEPTAM) and other government/PSU job applications.
Is accommodation available near the lab? TBRL provides nothing — no housing, no transport, no food allowance. Panchkula and Chandigarh have decent PG options but book ahead of time. July is a peak joining month across institutions.
What if I leave before 6 months? You get no certificate and no remaining payment. TBRL is clear — complete the full tenure or receive nothing. Plan accordingly before you apply.
The Bottom Line
37 seats. A DRDO certificate. ₹30,000 in hand. Six months of actual defence research experience.
And a deadline in days.
If you’re eligible, the only real question is whether you’re ready to commit to six months away from home in a structured, disciplined research environment. If yes — download the form today, get your HOD to sign the letter this week, and post it before the 25th.
