Product & Technology Development Centre (PTDC) - Powai


PTDC (D&A, Powai) is based in the Powai Campus of L&T and has a multi-skilled workforce with specialists spanning diverse areas of technology. These specialists are essential for successful product and technology development. At least a third of the total workforce has advanced degrees in specialised engineering areas.

The Centre has core capabilities in Technology Development, Concept Design, System Integration and Prototyping for the Defence & Aerospace Sector. The Centre is configured in functional groups which work in tandem to identify and incubate new technologies and products:

  • Electronics System Engineering & Hardware Development Group
  • Software Development Group
  • Naval Systems Engineering & Development Group
  • Land Systems Engineering & Development Group
  • Flight Systems & Composites Development Group
  • Analytical Engineering & Experimental Techniques Group
  • Project Management Group for Development Projects

The teams engage in highly interactive brainstorming and ideation sessions - these think tanks include people not only from within the department but also from engineering and manufacturing, with an end goal of generating a vast pool of innovative ideas. Senior management, with their knowledge and experience, plays a pivotal role in mentoring young minds and encourages them to come up new methods of achieving a design goal.

There is also a significant collaborative structure in place with various organisations like DRDO, ISRO and institutions like IITs, which helps us leverage the vast knowledge base available within the nation.

Facilities and equipment available at PTDC include:

  • Prototype Shop
  • Virtual Reality Facility
  • Hydraulics Lab
  • Embedded Software Development Lab
  • DSP / FPGA Lab
  • RF Lab with required instrumentation
  • Environment Test Chambers
  • Vibration Test Facility
  • Vibration, Noise & Strain Gauging Equipment
  • Technical Library

The key technologies developed thus far by the Centre include stabilisation technology (to stabilize weapon & sensors on ship platforms and stabilisation of ships using fin stabilisers), Ballistics of Field & Air Defence Guns, Algorithms for Automatic Bottom Avoidance for Sonar Winch Systems, Methodology for Multi Sensor Data Fusion using Multiple Hypothesis Tracker (MHT) and IMM filters, Image Processing Technologies such as Image Fusion, Image Stitching, Motion Detection & Image correlation. We have succeeded in commercializing a large number of these technologies through products supplied to customers such as the Indian Ministry of Defence.

The innovation culture at this centre has led to the development of over a hundred successful products such as PinakaMulti-Barrel Rocket Launcher WM-18Naval Rocket LauncherTriple Tube Torpedo LauncherDhanush Stabilised Launch SystemLand based weapon launchers including NAMICA, AACAR, AkashAdvanced Air Defence Launcher besides Radar platforms Rohini & RevathiNaval Engineering Systems including indigenous Winch & Sonar Handling SystemsSteering GearFin Stabilisers and more.

Areas of work and expertise in the PTDC-Electronics System Engineering, Hardware Development and Software Groups


Our process framework is designed in accordance with IEEE 12207 guidelines, with requirements governed by SEI CMMI Level-5 staged approach. CMMI (Capability Maturity Model Integration) is a proven industry framework that provides the Centre with the essential elements of processes to improve product quality and develop efficiency for both hardware and software. It is sponsored by the US Department of Defence, in co-operation with Carnegie Mellon University and the Software Engineering Institute (SEI).

PTDC has been appraised at Level 5 through an appraisal process carried out by KPMG in March 2016. An appraisal at maturity level 5 indicates that the group is performing at an “optimising” level. At this level, an organisation continually improves its processes based on a quantitative understanding of its business objectives and performance needs. The organisation uses a quantitative approach to understand the variation inherent in the process and the causes of process outcomes.
