          required in-house development.                                    Chuen, is due to the early vision of Dr Goh Keng Swee.
              By the late 1990s, it was clear to Peter Ho that DSO              Its first Director, the late Dr Tay Eng Soon, established
          had been transformed into a credible and internationally          an ethos and atmosphere conducive to science, which is
          benchmarked defence science R&D organisation.                     still a hallmark and signature of the organisation.
              In 1998, with the opening of the redeveloped Marina               Philip Yeo lent DSO his unique management style,
          Hill complex, came a landmark announcement which                  funding and manpower resources, and sense of freedom.

          glimpse of its capabilities.                                      DSO National Laboratories a truly great place for science.
              And this new public profile paralleled the development,           In the three decades, DSO has developed unique
          in the 1990s, of a large scientific R&D community in              capabilities in defence science – capabilities that will allow

          profile in order to attract the best and brightest researchers.       It may be said that Dr Goh’s vision has been fulfilled.
              In 1991, DSO took the first step towards autonomy,
          adopting the status of an Executive Agency. This gave it some
          autonomy, although the freedom to operate independently
          came only in 1997, when DSO was corporatised as DSO
          National Laboratories. Not until 2000, did DSO finally
          adopt an independent personnel scheme.
              In 2002, DSO National Laboratories is celebrating
          three decades of R&D for defence science and technology.

                                     It was when I was Head of Naval Plans. We were
                                 planning for a new ship for the Navy. It was a project,
                                                                                                What? You were not told what it was?
                                                                                                    Yes! It was on the ship but nobody was allowed

                                 planned for the project. And also, Springboard ushered in          It had a lot to do with a few people who

                                 things you see in the Navy today were derived from             the Navy.                                                     to the SAF?                                                  Yes, it gave an identity to the engineers.
                                 those days in Springboard.                                         The Navy thought very hard and deeply about                   It was not. I would say that one of the biggest          But I don’t think it made a great deal of difference

                                 This must be around the mid ’80s?                              very strong skills in terms of determining its requirements   essentially a close sensitive unit. It was referred to   was still separate because of the veil of secrecy that

                                 Navy had really assessed what it needed for a fighting                                                                       you were like an intruder!
                                 ship. Before that, we just bought whatever people told         Adversity is the mother...                                                                                             When did you lift this veil of secrecy?

                                       And this was the first time we really looked at the      when you look at the Navy plans in those days, you                Something like that. And it was very difficult to    matured to the point where we could discuss some
                                 environment. We looked at our operational requirements.        didn’t just see plans to acquire these things for so          deal with them. Because of DSO’s culture of secrecy,     of its activities. So in 1989, when we opened up
                                 And we determined what performance and weapon                  many hundred million dollars, but you also saw                you only met certain people, and you couldn’t meet       the first DSO building at Science Park, I remember
                                 systems the ship should have.                                  parallel supporting plans for manpower, training,             anybody else.                                            that Lee Hsien Loong, then Second Minister for
                                       There are two important things about the ship            doctrine development and R&D.                                     And the question was, how did you know               Defence, made some broad references to the
                                 which are germane to DSO.                                          So we allocated resources, meaning, funds and             what DSO was doing? Who to meet? That was                capabilities of DSO.
                                       One, was the conclusion that this ship should be         people, to support the R&D effort as well.                    the problem.                                                  This was followed by the opening of a
                                 equipped with electronic warfare (EW) systems.                     So, I would say that was something good for                                                                        second building at Marina Hill, I think it
                                 Because the conclusion was that, if you didn’t put on          DSO. Because certain areas like underwater warfare            The Defence Technology Group (DTG) was formed            was 1998.
                                 these systems, the ship would not have the capability          and electronic warfare – were to prove very critical.         in 1986. Did that change things?                              There was already very clear evidence, by
                                 to fight a modern naval battle.                                There was a sure base load for DSO, some years                     The formation of DTG shouldn’t be seen              1995, that DSO was a credible R&D organisation.
                                       The second very critical decision was that this new      down the line.                                                in isolation.                                            So this bit of publicity was not without basis.
                                 class of ships should have an underwater warfare capability.                                                                      What happened was in those days, a decision              And there was also another reason. Because
                                 This was the first time we went into underwater warfare        Did they deliver? Was your faith redeemed?                    was taken to rationalise the various technology and      we were at that point, in the mid ’90s, in steep
                                 systems. We had absolutely no experience in this field.            My own view is that EW is the kind of area                logistics groups in MINDEF. So they created DTG,         competition for good quality R&D manpower.
                                 This is the anti-submarine kind of thing.                      where you cannot buy the capability. It’s a black art,        which reported to the Deputy Secretary (Technology).     The other research organisations were growing,
                                       I think it was almost an act of faith that DSO was       very black. And just because companies sell you the                So it was already a clustering of the technology    and scientists and researchers were at a premium.
                                 able to deliver the goods! Because DSO did not have            system, doesn’t mean that they sell you the whole             departments into one group, and a re-ordering of              I was very concerned that, if DSO was so

                                 were doing in EW, was highly classified.                       So you really have to develop your own indigenous             under another.                                           joining DSO, at least not in the numbers and
                                       In fact, DSO had installed one system on our             capability in EW.                                                  It was just a bit of housekeeping. I wouldn’t       quality needed.

                                 careers with DSO?

                                 Why did you think of corporatisation?
                                                                                             it needed.

                                      When I returned, in 1995, what was most striking       phases. The first phase was DSO, a smaller, in fact less      overseas links.
                                 to me was how much progress DSO had made in six             controversial part, moving out in 1997. DTG was to                 Of course, I’m only the door opener. But some           which they can deliver
                                 years. It seemed that in the six years when I was           move out later, as DSTA. But that was not until 2000.         of our key partners are really at the top of their fields.
                                 away, DSO had taken off like a rocket!                           So DSO was corporatised in April ’97.                    Once we create a critical mass, establish a reputation,      what they promised.”
                                      Not just in EW, but in many areas, and as an                In the end, DTG went a different route. It became        it becomes relatively easy to go to others. So we spent
                                 organisation. It now had a whole range of areas.            a Statutory Board on 15 March 2000.                           a lot of time with the United States and with France,
                                 I was very encouraged to see that.                               Thus, we were not thinking about the corporatisation     trying to push this relationship.                            certain things secret. But, I think that the shift had
                                      And one of my conclusions was this: DSO was            of DSO in isolation. There was a plan to do it in two              One of the important things I suggested to              taken place. Maybe part of it was deliberate, part of it
                                 really a major component of SAF’s strategic advantage.      steps. That is, DSO first, then the rest of DTG afterwards.   DSO, and I remember this was very soon after DSO             just happened. But today, DSO is very open, you
                                      That DSO was supplying SAF with a technology edge.                                                                   National Laboratories was set up in 1997, was that           know, remarkably open.
                                      Now, if you share my conclusion, then you have         Do you have any advice for DSO for the future?                they should establish a DSO Advisory Panel. An                    I would say without a doubt, that today, DSO is
                                 to decide how you are going to sustain that advantage           There’s one more thing I should say about                 international one.                                           world class in certain niche areas.
                                 and how you are going to grow that advantage.               DSO. This relates to how you sustain and build up                  So we had this DSO International Advisory Panel              We saw it pick up in the early ’90s. I think
                                      We concluded that the competition for such             your capability.                                              for two years and they were quite an interesting lot.        corporatisation has helped it a lot. So we really saw
                                 manpower was getting more severe and it would do                One, you must invest in people. That’s why in                  There was Peter Levene who was once Director            a pickup in the last few years.
                                 us no good if we continued to have DSO operating as         one of my remarks, I said the key to DSO is people,           of Defence Procurement in the UK. He is now Lord

                                 the Ministry.                                                   But the other thing that I thought was very important     from 1998-99.                                                    Well, I think the future direction is more in terms
                                      I came to the conclusion that the critical thing was   and critical, was to get DSO to do more work with                  And we had Roger Hagengruber from Sandia, and           of moving DSO onwards, and building up capabilities
                                 people. DSO used a completely different type of talent      reputable R&D institutions overseas. Because that is          Bo Rybeck who used to be with the Swedish R&D                in new areas. Because there are always new areas
                                 from MINDEF and the SAF, and so was competing for           the only way you will know how good you are.                  establishment. We had Henry D’Assumpcao, who was             which DSO can build capabilities in.
                                 a completely different pool of manpower.                        I think in the last five years, in DTG as well as         Chief Defence Scientist of Australia. We had Moti                Today, DSO has reached the point in which they
                                      It was restrictive to have R&D people within           DSO, we have been able to give an enormous push               Heiblum from the Weizmann Institute in Israel.               can deliver what they promised, and I think the SAF

                                 regime as MINDEF and the SAF which are essentially              And there was a seminal speech, given by DPM                   So we had them for two years. First, I wanted           that you can publicise too much.

                                 Gordian knot.                                               NUS. Because that really spelt out how we see the             Laboratories, a group from outside to look at DSO.           competitive and strategic advantage.
                                      Basically we wanted to give DSO autonomy in its        basic, underlying approach to defence technology.             And to do a critique of DSO. I think they were quite             Because if you think about it, more and more
                                                                                                                                                           brutal in their assessments.                                 of our weapon systems today are not off-the-shelf.
                                                                                                                                                                And secondly, I wanted to get DSO used to                   I would say that the majority of our weapon

                                     This was why we started DSO. We were looking at         And they spent the time – after the 1967 war to the                I still remember his office at one corner of Pearl’s   and other countries and wrote a paper.

                                 our country’s economic development. And therefore,       DSO the flexibility it required. So after careful
                                 the growth must henceforth be through leveraging         study, in 1997, we decided that DSO should
                                 of the brains in the universities and through            be corporatised.
                                 overseas collaboration.                                      So we are evolving, because the whole time
                                                                                          we are learning. If things don’t work, we change.
                                 Why did DSO become an Executive Agency (EA)
                                 and why was it corporatised later on?                    What are your thoughts about the management
                                     The idea is very clear. That DSO, when it was        of R&D?
                                 part of MINDEF, and part of the Government, was               If you look at everything that is neat and tidy,
                                 encumbered by many rules and regulations. This           it’s not science. If you look at boxes, as soon as you
                                 slowed them down.                                        start drawing boxes, you have hierarchy, you are
                                     So they needed to have flexibility. And in           “fossilising” the organisation!
                                 the main, flexibility is two things. One is manpower –        You have to “Let one thousand flowers bloom!”
                                 how to recruit manpower according to your needs.              At a certain stage you are still planting, you are
                                 And you must be able to fire them if they don’t do       ploughing, you are putting seeds in, and seeing nothing!
                                 a good job. So you must be able to manage and                 You pour water, put more seeds in, add fertiliser,

                                                   Another interesting application was the use of NLP for question answering (QA).
                                             In a traditional search engine (similar to engines such as Google on the Internet), the
                                             user types in a keyword and the engine retrieves a set of documents which contains
                                             the keyword. For QA, NLP techniques were employed to handle questions like “Who is
                                             the President of Singapore?”. The NLP module analyses the words in the question to
                                             provide another level of information besides these words. For example, DSO’s QA




                                                                                                                   .
                                             module would know that the question, “Who is the President of Singapore“, is asking
                                             for a person (from the word “who”), and would also know that “President” is a title and
                                             “Singapore” is a country. The QA engine will attempt to return the sentence within the
                                             target document that contains the answer to the question. This is more precise than
                                             what current search engines provide i.e. just the document itself.

                                   Integrated warfare derives its power
                             from the networking of dispersed forces
                             through an enabling information backbone
                             which gives full access to smart sensors,
                             and enhances the precision and speed of
                             response of shooters. DSO is continuing its
                             drive towards the mastery of the critical
                             enabling technologies necessary for the

                             force operating in air, land and sea, which
                             is capable of dynamic engagement in all
                             directions and at all times.
