<h3>Important Facts</h3>
<p>The fully <span class="key-term" data-definition="reusable launch vehicle — A rocket designed to be recovered and flown again, reducing launch cost (GS3: Economy – key to cost‑effective space access).">reusable launch vehicle</span> has cost more than <strong>$15 billion</strong> to develop. It is central to Musk’s strategy of cutting launch costs, expanding the <span class="key-term" data-definition="Starlink — SpaceX’s broadband satellite constellation aimed at providing global internet connectivity (GS3: Economy – represents a commercial venture with revenue implications).">Starlink</span> business, and pursuing deep‑space projects such as lunar landings and orbital data centers. The venture is also tied to a planned <span class="key-term" data-definition="IPO (Initial Public Offering) — The first sale of a company’s shares to the public, used to raise capital; SpaceX’s planned $1.75 trillion valuation makes it the largest IPO ever (GS3: Economy).">IPO</span> valued at <strong>$1.75 trillion</strong>, which would be the biggest public offering in history.</p>
<p>Musk reassured investors that a failure would not disrupt the launch cadence by more than a month, citing a “large pipeline of V3 ships and boosters” in the factory.</p>
