Roughly 10,000 new defense companies have entered the market in the past two years, according to an analysis by the Center for Strategic and International Studies. So-called nontraditional companies, which include venture-backed startups and also small businesses and commercial tech companies, received over $122 billion in the prior fiscal year, double the amount from a decade prior. But during that same period, the Pentagon also doubled its spending on traditional primes, as the top-tier mega defense contractors are known, to $372 billion, the CSIS analysis shows.
