The Protective Technology Research (PTR) Team, comprising members from the Defence Science and Technology Agency (DSTA), the Nanyang Technological University (NTU) and the National University of Singapore (NUS), has built up a strong in-country capability in the protective technology. Over the years, this team has embarked on several bold initiatives. They developed innovative technological concepts and solutions to enhance the protection of defence facilities and critical infrastructure. Their research work not only contributed to the long-term security of our nation, it has also demonstrated how technology can be exploited creatively in the optimisation of land use in Singapore. Through their research efforts, Singapore now enjoys a good international standing in the area of protective technology.
